canvas.js: LCH colorspace (thanks Robert Simmon @ OpenVis Conf)
pattern.metrics readability() type checking
pattern.text find_keywords() takes optional parameters

update unit tests
canvas.js small adjustments to Color, renamed LCH to HCL.
pattern.db Datasheet.columns.sort() with reverse=True now works
pattern.text support for word frequency lists
multilingual word frequency lists

Frequency lists (e.g., pattern/text/en/en-frequency.txt) contain relative document frequency for common words. This gives us better keyword extraction with, for example, pattern.en.keywords().
pattern.vector BPNN classifier (backprop neural network, slooow)
