fixed some other UI logic in the python menu script
Added an option to use a vertex group for a reduction weight map to force reducing some areas more then others.
Mesh epydocs activeGroups can be None as well as string.
made ngon loop-reduce function faster by replacing dicts with sets
off_export has some errors, modernized the script.
added a python 2.3 reversed compat function - just uses ls[::-1]
Further 2.3 compat testing needed.
Added remove doubles as a keyword option,
Fixed Triangulate (need to select the faces first)
Fixed boundry weighting (defaults reduced boundries first more then
non boundry verts!)
Made face area weighting give better results.
Workaround for a problem where badly predicted positions are further then half the edge length, on these cases just collapse to the weighted middle of teh edge.
Added docs for "PolyReduce" (Uses BPyMesh_Redux) and WIP Docs for AutoTex Layout.

~20% faster and memory saved by re-using the face and edge lists and their classes each pass rather then __init__'ing new ones.
Stupid mistake- was only collapsing edges with UV's
Added support for "Weighted Collapse" Before an edge could only collapse into its middle,
Now the edge collapses into a point bias'd by the 2 verts Concave/Convec "Pointyness" value as well as boundry weighting.
This works much better for boundry verts. - UV's Vcols and Weights are correctly interpolated into the new location.
Added a tool in the mesh menu for accessing the poly reduction tool.
fixed some bugs in BPyMesh_redux, tweaked to work well for test cases. much better use of error levels for edge weighting. better collapsing to the desired target. triangulates before reduction be default now.
* Much improved, slower edge collapse weighting method that makes this script about 2.5x slower, but brings it up to the quality of qslim (lightwave's decimator), without the manifold' errors.
Probably worth adding a UI front end to this function.
Isnt intended to be ultra high quality, more for automatic realtime "Level of Detail" model generation.
BPyMesh.redux(ob, 0.5) # To reduce to about half the polys
