Previous multi-sub-element linking (e.g. Face, Edge) is supported
through SubElements of type PropertyStringList, which does not support
geometry element update tracking. This patch changes it to use
PropertyXLink's new multi-subname capability.

ViewProviderAttachExtension::extensionMergeOverlayIcons() calls
AttachExtension::positionBySupport() which will always touch the
extended object. This may cause recomputation problems, e.g a datum
that is always touched, because normal recomputation trigger tree
view update by a timer, tree view refreshes the icon, datum gets
touched again.
Calls to BSplineSurface.buildFromPolesMultsKnots() with explicit knots or weights fail in recent versions of FreeCAD (tested on 0.18.3 with python3) with the message 'The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()'.
This trivial change follows the pattern used later in the function of explicit comparisons with Py_None, replacing PyObject_Not() and PyObject_IsTrue() when they are used to determine whether explicit weights or knots have been provided.
* Added Part::Feature::getTopoShape/getShape() function that can obtain
shape from any object with proper implementation of getSubObject(). It
can even construct compound from group object with proper implementation
of getSubObjects().
* Modified ViewProviderExt to work on any object, because it now obtain
the shape using Part::Feature::getShape()
* Modified various Part features to obtain base/tool shapes using
Part::getShape(), which allows them to be any type of object,
including Link and groups.
* Modified various Part command to relax type requirement on selected
objects.
* Add support of link and group to dimension, and add dimension refresh
command
* Support link and group in simple command command, and add a few more
copy command variations.
* Add special handling of 'Shape' attribute in PropertyContainerPy and
use Part::Feature::getShape() to return shape for any object without
Shape property. This allows many python feature work with any object
without modification.
* GeometrySurface/CurvePy, add convenience attribute 'Rotation'
* TopoShapePy:
* Extended support of sub shape attribute, e.g. Compound1, Solid2,
SubShape3 ('SubShape' is used to access child shape of a compound)
* makeWires(), new API to sort and return wires given a list of edges.
* transformed/translated/rotated/scaled(), return a new shape with
some transformation.
* findPlane(), find the plane of a planar shape
* isCoplanar(), check if two shape are coplanar
Implement box element selection that support linked and grouped objects.
Also modified original box selection command to support the same with
the same code.
DocumentObject:
* getSubObject(): the most important API for Link to work with
hierarchies. The function is a inspired from and replaces the
getPySubObjects(). It returns a child object following a dot separated
subname reference, and can optionally return accumulated
transformation, and/or a python object of the refered
sub-object/element. The default implementation here is to look for
link type property, and search for the referenced object. This patch also
include other specialized implementation of this API, such as
(GeoFeature)GroupExtension (through extensionGetSubObject()),
PartDesign::Body, and so on. A link type object is expected to
call the linked object's getSubObject() for resolving.
* getSubObjectList(): helper function to return a list of object
referenced in the given subname.
* getSubObjects(): return a list of subname references of all children
objects. The purpose of this function is similar to
ViewProvider::claimChildren(). Container type object is expected to
implement this function. The reason it returns subname references
instead of just object is to allow the container to skip hierarchies.
For example, the Assembly3 container uses this to skip the constraint
and element group.
* getLinkedObject(), obtain the linked object, and optionally with the
accumulated transformation. It is expected to return a linked object
or the object itself if it is not a link. In case there are multiple
levels of linking involved, this function allows the caller to retrieve
the linked object recursively.
* hasChildElement(), set/isElementVisible(), controls the children
visibility for a group type object. Because the child object may be
claimed by other objects, it is essential to have independent control
of children visibilities. These APIs are designed to abstract how
group manages the child visibility. For performance reason, these
function are meant to control only the immediate child object.
* resolve(), helper function to parse subname reference and resolve the
final object, and optionally the immediate parent of the final object,
the final object reference name (for calling `set/isElementVisible()`),
and the subname reference if there is one.
* touch(), add optional argument 'noRecompute' for better backward
compatibility with the NoRecompute flag. By default, touch() causes
recompute unless noRecompute is true
* signalChanged/signalBeforeChange, two new signal for tracking changes
of a specific object.
* getViewProviderNameOverride(), return a string of the view provider
type of this object. This allows Python class to override the view
provider of an object. This feature will be used by ViewProviderLink
which is designed to work with any object that has LinkBaseExtension.
* canLinkProperties(), will be used by Gui::PropertyView to display
linked object properties together with the object's own properties.
* redirectSubname(), will be used by Gui::Tree to allow an object to
redirect selection to some other object when (pre)selected in the tree
view.
* Visibility, new property serve as the same purpose as view provider
property of the same name. It is added here so that App namespace
code can check for visibility without Gui module. This is useful,
for example, when constructing a compound shape of a container that
respects the children visibility.
* (has)hasHiddenMarker(), return or check for a special sub-element
name used as marker for overriding sub-object visibility. Will be
used by Gui::ViewProvider, it is put here for the same reason as
adding Visibility property.
* getID(), return object internal identifier. Each object is now
assigned an integer identifier that is unique within its containing
document.
Document:
* ShowHidden, new property to tell tree view whether to show hidden
object items.
* signalTouchedObject, new signal triggered when manually touch an
object when calling its touch() function
* getObjectByID(), get object by its identifier
* addObject() is modified to allow overriding view provider
* has/getLinksTo(), helper function to obtain links to a given object.
Application:
* checkLinkDepth(), helper function to check recursive depth for link
traversal. The depth is checked against the total object count of
all opened documents. The count (_objCount) is internally updated
whenever object is added or removed.
* has/getLinksTo(), same as Document::has/getLinksTo() but return links
from all opened documents.

========================================
Generalisation of code for a default geometry extension in the form of a template.
Default geometry extensions provide a standard interface for an extension having a single stored value (e.g. one int or one string).
Python implementation must be provided separatedly.
=======================================
unique_ptr is a move only type. Therefore it may only take an rvalue.
It does not make sense a pass by value for move only types (Item 41).
==============================================================
When the geometry object is destroyed, std::vector's destructor is called, which in turn calls the destructor of the smart pointers.
If a weak_ptr corresponding to one of those shared_ptr is locked (elsewhere, if FC were multithread),
the underlaying resource will not be freed until said locked weak_ptr goes out of scope. It will then.
