Add DraftObject and ViewProviderDraft to serve as
the parent classes of all Draft objects
and all Draft view providers.
Inside `Draft.py` we need to import
`_DraftObject` from `draftobjects.base`;
and `_ViewProviderDraft`, `_ViewProviderDraftAlt`,
and `_ViewProviderDraftPart` from `draftviewproviders.view_base`.

Occasionally it fails to join lines even if the lines
visually share a point.
This is a rounding error in the comparison of the shared point;
a small distance will result in the points being considered
different and thus the lines not joining.
The solution is to test properly the two points using
`DraftVecUtils.equals` which considers the value of
the `precision` set in the Draft preferences.
still have to split viewprovider from object.
[Draft] Dimension Style code cleanup
thx @vocx-fc for reviewing
further cleanup
[Draft] Dimension Style improvements
Added a property to the dimension object to link the dimension style.
Improved the update of dimensions when style changes. This can be done in 2 different ways: by setting AutoUpdate property to True or by activating Update function from the viewprovider context menu.
The changes are minimal, mainly is just cleanup of existing code and documentation.
[Draft] Annotation scale for ViewProviderDraftText
Adding support for scale factor according to changes in dimensions.
[Draft] Annotation scale for ViewProviderDraftLabel
completed annotations scale
[Draft] Annotation scale for ViewProviderAngularDimension
If it is a linear dimension show the older icon;
if it is a radius or diameter dimension show a new icon.
These three modes use the same Proxy class
and the same viewprovider class. Depending on the linked geometry
one icon or the other will be shown.
When there are many Draft objects in the tree view
the icon can be used to tell different objects apart quickly.
One icon is used for objects that are "straight lines",
whose Proxy is of type `Line`, `Wire` or `Polyline`; another icon
for "regular geometrical" shapes of type `Rectangle` or `Polygon`;
and another icon for "curved" objects of type `Circle`,
`Ellipse`, `BSpline`, `BezCurve`, or `Fillet`.
Other objects use the older default icon.
Inside the class `_DraftLink` the `onDocumentRestored` function
tests for the existence of the old attribute `useLink`. If it is
present, it uses it to define the new variable name `use_link`.
This is done use Python naming conventions.
The old `useLink` is deleted so it is not longer saved
together with the object when the document is saved.
The linear and radial dimensions use the same Proxy class,
but the angular dimension uses a different Proxy class.
To recognize quickly in the tree view the different
types of dimensions, we provide a new icon.
The icon is inspired on the `Draft_Dimension.svg` and
`TechDraw_AngleDimensions.svg` icons.
There was semantic change of the division operator ‘/’
from python2 to python3. This fix makes the circular array
work with python2 correctly.
See PEP 238
The translate mechanism in Draft depends on the `QtCore`
`translate` function. This is defined in its own module
so that `DraftGui.py` is not as big and hard to manage.
Other modules in Draft can import the translate function
without needing to import the entire interface, which
often causes errors and circular dependencies.
We can import `QtCore.QT_TRANSLATE_NOOP` at the top level
in `Draft.py` because it does not depend on the graphical
interface.
Many auxiliary tools used by `Draft.py` can be defined
in another module. Many functions are moved to this module
so that `Draft.py` isn't as big and hard to maintain.
The following is a list o functions that were moved:
`get3DView`, `autogroup`, `dimSymbol`, `dimDash`,
`removeHidden`, `formatObject`, `getSelection`,
`getSelectionEx`, `select`, `loadTexture`.
Moreover, many of these functions were renamed
to comply better with PEP8 guidelines,
particularly the use of `snake_case`. For example,
`get3DView` is now `get_3d_view`.
Aliases are provided for the old names so that
other functions and classes that depend on these
won't break. The new names should be the official
programming interface, while the old names
should be deprecated at some point in the future.

Auto add object to part container if active and if no other autogroup object is selected by the user.
Note that object placement is automatically corrected to not jump over space.
