Defines the "Source Shape 3D" hypothesis, specifying a meshed solid, from where the mesh pattern is taken, and, optionally, the association of vertices between the source and the target solid (to which a hipothesis is assigned)

Parameters:

solid	from where the mesh pattern is taken
mesh	from where the mesh pattern is taken (optional)
srcV1	a vertex of solid to associate with tgtV1 (optional)
tgtV1	a vertex of the solid where the algorithm is assigned, to associate with srcV1 (optional)
srcV2	a vertex of solid to associate with tgtV1 (optional)
tgtV2	a vertex of the solid to which the algorithm is assigned, to associate with srcV2 (optional)
UseExisting	- if ==true - searches for the existing hypothesis created with the same parameters, else (default) - creates a new one

Note: association vertices must belong to one edge of a solid
