	Read a graph from a .tgf file.

bool	igl::readTGF (const std::string tgf_filename, Eigen::MatrixXd &C, Eigen::MatrixXi &E, Eigen::VectorXi &P, Eigen::MatrixXi &BE, Eigen::MatrixXi &CE, Eigen::MatrixXi &PE)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Detailed Description

.tgf - control handle graphs

A .tgf file contains a graph of describing a set of control handles/structures: point controls, bones of a skeleton and cages made of "cage edges".

The first part of the file consists of lines regarding each vertex of the graph. Each line reads:

[index] [x] [y] [z] [undocument optional data]

Indices begin with 1 and should proceed in order. Then there should be a line with a sole:

The next section concerns the edges of the graph. Each line corresponds to an edge:

[source index] [dest index] [is bone] [is pseudo-edge] [is cage edge] [undocument other data]

Bone edges trump pseudo and cage edges.
