extract child mesh from tag

[JcDai]

add generic functions to extract a child mesh from a provided long-type tag (or its handle), and register the extracted child mesh to the parent mesh. (The child mesh should not break the orientation of the parent mesh)

• extract child mesh by tag
• extract child mesh by tag handle
• generalize the functions
• check if the orientation keeps in the childmesh

[JcDai]

need to check if the current implementation of filling the child mesh matrix (by simply switch vertex/edge from a ccw tuple) preserves the orientation for all possible cases.

The functionality is there. Just clean it up and you're good to go.

Please be a more careful about when to use which integer data type. int,long, and size_t are not the same thing.
