BarycentricMapping
------------------

Context: Sofa.Component.Mapping.Linear

Mapping using barycentric coordinates of the child with respect to cells of its 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
 - useRestPosition : Use the rest position of the input and output models to initialize the mapping

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
 - mapper : Internal mapper created depending on the type of topology
 - input_topology : Input topology container (usually the surrounding domain).
 - output_topology : Output topology container (usually the immersed domain).
