Class RussianCharsets

RussianCharsets class contains encodings schemes (charsets) and toLowerCase() method implementation for russian characters in Unicode, KOI8 and CP1252. Each encoding scheme contains lowercase (positions 0-31) and uppercase (position 32-63) characters. One should be able to add other encoding schemes (like ISO-8859-5 or customized) by adding a new charset and adding logic to toLowerCase() method for that charset.
