RigidMapping
------------

Context: Sofa.Component.Mapping.NonLinear

Set the positions and velocities of points attached to a rigid parent

Data:
 - name : object name
 - printLog : if true, emits extra messages at runtime.
 - tags : list of the subsets the objet belongs to
 - bbox : this object bounding box
 - componentState : The state of the component among (Dirty, Valid, Undefined, Loading, Invalid).
 - listening : if true, handle the events, otherwise ignore the events
 - mapForces : Are forces mapped ?
 - mapConstraints : Are constraints mapped ?
 - mapMasses : Are masses mapped ?
 - mapMatrices : Are matrix explicit mapped?
 - applyRestPosition : set to true to apply this mapping to restPosition at init
 - geometricStiffness : Method used to compute the geometric stiffness:
-None: geometric stiffness is not computed
-Exact: the exact geometric stiffness is computed
-Stabilized: the exact geometric stiffness is approximated in order to improve stability
 - initialPoints : Local Coordinates of the points
 - index : input DOF index
 - filename : Xsp file where rigid mapping information can be loaded from.
 - useX0 : Use x0 instead of local copy of initial positions (to support topo changes)
 - indexFromEnd : input DOF index starts from the end of input DOFs vector
 - rigidIndexPerPoint : For each mapped point, the index of the Rigid it is mapped from
 - globalToLocalCoords : are the output DOFs initially expressed in global coordinates

Links:
 - context : Graph Node containing this object (or BaseContext::getDefault() if no graph is used
 - slaves : Sub-objects used internally by this object
 - master : nullptr for regular objects, or master object for which this object is one sub-objects
 - input : Input object to map
 - output : Output object to map
