Coverity CID 350580: Uninitialized scalar variable. The analyzer doesn't like the incomplete construction of the ConstraintId object (the 'Type' field was uninitialized).
===================================================
This commit is an independent refactor of the identifications used at Sketcher level.
It introduces a new type "GeoElementId" as a combination of GeoId and PointPos.
It moves the Undefined GeoId, previous Constraint::GeoUndef to GeoEnum, together with all
other fixed values of GeoIds.
=============================================================================================
This commits removes the Geometry construction data member and adapts sketcher code to use
GeometryFacade to access construction information via the SketchGeometryExtension.
A series of algorithms to detect missing constraints and create them.
Each of the algorithms is divided in different steps for maximum flexibility:
/// There is a first type of routines, simple routines, which work in the following order:
/// Detect - (Analyse) - [Get] - [Set] - Make
///
/// The Detect step just identifies possible missing constraints.
///
/// The Analyse, which is not available for all the routines, operates in detected constraints of the same routine, to
/// look for alternatives. For example, a general pointonpoint detection leads to a search for coincident constraints, which
/// can be later run via Analyse if it is intended to convert endpoint coincidence to endpoint perpendicular and tangent constraints.
///
/// The Get retrieves the result of the analysis as a vector of ConstraintIds, indicating the suggested constraints. This step is intended
/// for enabling the user to check the result of the analysis, rather than applying it. If only applying is intended, this step is not necessary
/// as the Make will operate on the result of the Detect - Analyse directly.
///
/// The Set changes the detected result. It modifies the SketchAnalysis object. It only modifies the SketchObject as far as the SketchAnalysis is changed.
/// It does not apply any changes to the sketch. It is intended so as to enable the user to change the result that will be applied.
///
/// Neither the Detect, nor the Analyse, nor the Get steps modify the Sketch geometry.
///
/// Make applies the constraints stored internally in the SketchAnalysis object.
It includes an automatic constraining algorithm for coincidences, horizontals/verticals and equality:
/// A second type of routines, complex routines, are thought for running fully automatic and they Detect, Analyse and Make.
/// They may also apply a variaty of types of Constraints.
It also includes some helper functions, like autoRemoveRedundants
