/**
* Returns true if the string matches the specified shell
* expression.
*
* Actually, currently the patterns are shell expressions,
* not regular expressions.
*
* Examples:
*
* ``` js
* shExpMatch("http://home.netscape.com/people/ari/index.html", "*\/ari/*")
* // is true.
*
* shExpMatch("http://home.netscape.com/people/montulli/index.html", "*\/ari/*")
* // is false.
* ```
*
* @param {String} str is any string to compare (e.g. the URL, or the hostname).
* @param {String} shexp is a shell expression to compare against.
* @return {Boolean} true if the string matches the shell expression.
