 *  DESCRIPTION: Simple string tokenizer class.  Stores the strings parsed from
 *               another string as an array of strings.  Pass the legal delimiters
 *               as the second argument to the second constructor.  Whitespace is
 *               preserved.  To eliminate whitespace, use CSimpleStringBase::Trim()
