PlasticSkeletonDeformation models the deformation of a group of PlasticSkeleton instances.
\par Description
A PlasticSkeleton instance is typically used to act as a deformable object - in other
words, it defines the 'original' form of a hierarchy of vertices that can be manipulated
interactively to obtain a 'deformed' configuration.
\n\n
PlasticSkeletonDeformation represents a deformation of PlasticSkeleton objects,
therefore acting primarily as a collection of PlasticSkeletonVertexDeformation
instances - one per skeleton vertex. The collection is an associative container mapping a
<I> vertex name <\I> to its deformation; using names as keys is a useful abstraction
that allows vertex deformations data (eg keyframes) to be copied to skeleton deformations
whose skeletons have a different internal configuration (ie vertex indices and such).
\n\n
Each vertex deformation also stores a unique <I> hook number <\I> that can be used during
xsheet animation to link stage objects to a skeleton vertex.
\par The Skeletons group
The PlasticSkeletonDeformation implementation has been extended to work on multiple
skeletons for one class instance. This class stores a map associating skeleton indices
to the skeleton instances, that can be used to select a skeleton to be deformed with
the deformation's data.
\n\n
Vertices in different skeleton instances share the same animation if their name is the same.
\n\n
This class provides an animatable parameter that is intended to choose the \a active
skeleton along an xsheet timeline. It is retrievable through the skeletonIdsParam() method.
\par Notable implementation details
In current implementation, a PlasticSkeletonDeformation keeps shared ownership of the
skeletons it is attached to. It is therefore intended to be a \a container of said skeletons.
