+temp loader allows some lua requires to be loaded and later garbage collected
+unfortunately the module needs to be formatted in such a way to pass back a 
+call table in order to keep the functions within from being garbage collected 
+too early
+
+BE AWARE this bypasses the module loader which would allow code reuse
+so if you aren't careful this memory saving tool could spell disaster
+for free RAM if you load the same code multiple times
