Detailed Description

template<typename T>
class meshpatchptr< T >

Functional object to return control points, but can point to different mesh patches.

The index interprets the line of control points as a 2D matrix.

Initialize in construction phase. Use indexSet(...) to point to different mesh patches.

There is no error checking, for example on index bounds.
