Renamed anything() to something().
Added anything(), any(), notWhitespace(), notDigit(), notDigits(),
notLetter(), notLetters().
Fixed python naming convention.
either and or are now overloaded instead of having eitherLike and
orLike.
Python now has either() method that accepts mixed-type array of strings
/ RegExpBuilder objects instead of all of the either_string, or_string,
either_like, or_like methods.
Merge remote-tracking branch 'upstream/master'

Conflicts:
