--- received arguments ---
int               n_vertices,         --- number of vertices
const PK_VERTEX_t vertices[]          --- acorn vertices to delete
)


This function deletes the given acorn vertices.


Specific Errors:
    PK_ERROR_not_general          vertices do not belong to a general body


The vertices must all be from the same general body and should be acorn.  The
vertices are deleted from this body.  Specifying vertices which are not acorn
vertices will have no effect on those vertices.
