Clear out all the cfml code (cfm, cfcs) in the cache of compiled code (aka the PagePool)
This function does not take any arguments.
In 5.3, this only clears the cache for the current Application, plus all Server and Web Context mappings.
Other Application caches are not cleared
This will be changed in Lucee 6
result = PagePoolClear(); echo(result); // page pool has been cleared
