    Usage void empty_cache ()
    Purpose To empty out the read-table-cache used by txtSQL at runtime
    Availability txtSQL >= 2.2.2 RC2

    When txtSQL first reads a table, it reads it and saves it to memory, because large tables consume time to read and parse. If you want to empty the cache (which only exists during run-time), use this function to erase it.
