Releases all free memory held internally by CLIPS back to the operating system. CLIPS will automatically call this function if it is running low on memory to allow the operating system to coalesce smaller memory blocks into larger ones. This function generally should not be called unless the user knows exactly what he/she is doing (since calling this function can prevent CLIPS from reusing memory efficiently and thus slow down performance). This function returns an integer representing the amount of memory freed to the operating system.
