Private Methods

Method	Description
advance_1 ( &$i, &$prevlen, &$thislen )	A private helper method for executeScript that advances the character by 1. In psql this is careful to take into account multibyte languages, but we don't at the moment, so this function is someone redundant, since it will always advance by 1
