/*  This class provides fast methods for checking whether a character is a
    member of a given character set (e.g., isAlpha()) and for translating
    characters (e.g., toUpper()). These functions are faster than their system
    library counterparts since they restrict their arguments to Uint8. For
    example, the system isupper() takes an int argument and must check to see
    if the int is between 0 and 128 before using it as an index into a table.
    Also, nearly all system implementation require an extra AND operation since
    a single table is used to implement all of the ctype functions (one bit
    per function).

    This class also implements additional functions not supported by the
    system library, like isAlphaUnder(), and isAlNumUnder(). Expression like
    this:

        if (isalpha(c) || c == '_')
            ...

    Become this:

        if (CharSet::isAlphaUnder(c))
            ...

    The optimization is even faster than it looks. Recall that isalpha() incurs
    an extra branch and an extra AND operation, as explained above.
