/**
 * This method will take a string of characters that you do not want to
 * appear in your string.  It will remove the unallowed characters and then
 * return to you the string as it would be without those characters.  For
 * instance if you passed ":" as the unallowed characters, and "I a:m ::Cle:an"
 * is the string you passed, you would end up with "I am Clean".  It does 
 * not replace the characters it removes them.
 * /*from   w ww. ja v a2s.co m*/
 * @param unallowableCharString --give me a string of all the chars you don't want in your
 * final string.
 * @param stringToClean  --this is the string that you want cleaned
 * @return  your new string
