/** \brief This class provides the structure to build a correspondence between 2 geometries.

  *

  * This correspondence is done at the vertex level. Which means that for each vertex in the

  * source geometry, you can have from 0 to N corresponding vertices in the destination

  * geometry. Each corresponding vertex is weighted.

  *

  * For example, if the source geometry is a NURB and the destination geometry is a mesh,

  * the correspondence object will express the correspondence between the NURB's control vertices

  * and the mesh's vertices.

  *

  * If the mesh corresponds to a tesselation of the NURB, the correspondence object can be used

  * to transfer any deformation that affect the NURB's control vertices to the mesh's vertices.

  *

  * See KFbxWeightedMapping for more details.
