Major refactoring to eliminate the redundant HE_Edge. An edge is defined
by one half of a halfedge pair, this halfedge will return TRUE when
queried by isEdge().
And poof, HE_Edge is gone. Now ready to tackle the undoubtedly
gazillions of related bugs.
Removed printl statements. Started implementation of Log4j logging
Renamed the mess of face subdivisions in HE_Mesh: splitFace(s)Something
WOrking out a bug with splkt edge labelling
Fixed a bug where an edge on a slicing plane didn't get the proper
label.
1. Made parameters of HET_BlaWriter uniform so in HET_Export path and
filename should be specified without extension.
2. Fixed a critical bug in triangulation that could result in flipped
faces
