Class ResidualStrokeCountExtractor

To Do (Lang): Implement, find a good algorithm to turn down unwanted forms, don't just choose random one. See the following list:

>>> from cjklib import characterlookup
>>> cjk = characterlookup.CharacterLookup()
>>> for char in cjk.db.selectSoleValue('CharacterRadicalResidualStrokeCount',
...     'ChineseCharacter', distinctValues=True):
...     try:
...         entries = cjk.getCharacterKangxiRadicalResidualStrokeCount(char, 'C')
...         lastEntry = entries[0]
...         for entry in entries[1:]:
...             # print if diff. radical forms and diff. residual stroke count
...             if lastEntry[0] != entry[0] and lastEntry[2] != entry[2]:
...                 print char
...                 break
...             lastEntry = entry
...     except:
...         pass
