syls2css

 syls2css: Find the confusing syllable set (CSS) from a given Mandarin syllable sequence in HanYu PinYin.
    The output CSS is obtained by analyzing Mandarin utterances of native Japanese.

    Usage: output=syls2css(syl)
           output=syls2css(syl, dict)

    The second usage will remove the confusing syllables that are not in the dict.

    For example:

        syls={'ren', 'men'};    % 人們
        css1=syls2css(syls)
        dictFile='hanyu.dic';
        dict=dictRead(dictFile);
        css2=syls2css(syls, dict)
