Log Message:
-----------
Added vexi.system.gc() and vexi.system.memoryusage() for application
debugging/development use.
Example usage:
var mem = vexi.system.memoryusage();
vexi.log.info("mem.maxMemory:" + mem.maxMemory);
vexi.log.info("mem.totalMemory:" + mem.totalMemory);
vexi.log.info("mem.freeMemory:" + mem.freeMemory);
vexi.system.gc();
