Attempt to split mesh using a curve network by scripting, that is suppose to be quite easy to do in other 3d packages but not in maya. This will be wrapped as a maya node eventually. Many problems to fix before production use, see todo.

change log:
20091127 first attempt using mel
20101206 first working attempt using python+Maya API on one curve
20110129 working with multiple curves and as a node
20110217 fix some problems with intersections on vertices (shown in orange) not splitting (testBuild)
todo:
fix issue with vec intersect that cause problems in mesh split
cookie cutter – i.e. internal shape without intersecting edges
internal loose ends during the process (not sure how to deal with this)
work with offset curves
testBuild as node

update on 20110409
development stalled
maya 2012 now has new function added as project curve on mesh and split mesh with projected curve
