BE_StackPush ( name ; value )
A stack is an internal plugin storage type, where you push data into a stack ( like a list of values ) and Pop data out. In the plugin, stacks are LIFO ( Last In First Out ) so when you push a value onto the named stack, it will be the next value to POP out of the stack.
Version : 4.1
name : the name of the stored stack. Stacks have names, much like variables do.
value : the value to store in the stack.
Result : just returns you back the value you sent it, and creates the stack name to store it in if it doesn't exist.
