/** match matches a string against a GLOB style pattern.

Return trues if the String parameter matches the pattern. C-Shell style

glob matching is used.

@param str String to be matched against the pattern

@param pattern Pattern to use in the match

@return Boolean true if str matches pattern

The pattern definition is as follows:

<pre>

* Matches any number of any characters

? Match exactly one character

[chars] Match any character in chars

[chara-charb] Match any character in the range between chara and charb

</pre>

The literal characters *, ?, [, ] can be included in a string by

escaping them with backslash "\". Ranges of characters can be concatenated.

<pre>

examples:

Boolean result = String::match("This is a test", "*is*");

Boolean works = String::match("abcdef123", "*[0-9]");

</pre>

/** matchNoCase Matches a String against a GLOB style pattern independent

of case.

Returns true if the str parameter matches the pattern. C-Shell style

glob matching is used. Ignore case in all comparisons. Case is

ignored in the match.

@parm str String containing the string to be matched\
