Merge branch 'master' of https://github.com/John07/paperwalking into german-merge
Just detecting image blobs so far without model comparisons
Experimenting with numpy for iterating over inter-blob triangle features
Working on angles
Redefined meaning of diatance ratios somewhat
Wrapped blob extraction into imgblobs() and included some assumptions about the blob sizes we want.
Started moving triangle-features.py code to featuremath module
Finishing moving logic from triangle-features.py to functions in module featuremath
Trying to cut down on the size of potential comparison universe early
Seemingly have gotten this new generator function working
Big cleanup
Added better docstring to featuremath.blobs2features()
Fixed tests and made imported functions not clutter up help()
Reduced some array-craziness in blobs2features()
Updated for recent featuremath changes
Added feature() function to explicitly generate ratios and thetas from points
Apparently deteching actual features
Introduced explicit Blob class so there are fewer tuples flying around
Simplified lots of feature math with new Point and Vector classes
featuremath.feature() now returns re-ordered points
