Added a cleaner solution for string replacement woes (ie, use Str.replace() instead of applying replace(/\$/g, "$$$$") to replacement strings)

+     * The JavaScript replace() function ALWAYS interprets "$" specially in replacement strings, even when
+     * the search string is NOT a RegExp; specifically:
+     *
+     *      $$  Inserts a "$"
+     *      $&  Inserts the matched substring
+     *      $`  Inserts the portion of the string that precedes the matched substring
+     *      $'  Inserts the portion of the string that follows the matched substring
+     *      $n  Where n is a positive integer less than 100, inserts the nth parenthesized sub-match string,
+     *          provided the first argument was a RegExp object
+     *
+     * So, if a replacement string containing dollar signs passes through a series of replace() calls, untold
+     * problems could result.  Hence, this function, which simply uses the replacement string as-is.
+     *
+     * Similar to the JavaScript replace() method, this replaces only one occurrence (ie, the FIRST occurrence);
+     * it might be nice to add options to replace the LAST occurrence and/or ALL occurrences, but we'll revisit
+     * that later.
