BE_StackDelete ( name )
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.
This function deletes the stack called name regardless of how many values it has in it. Mostly only for cleanup purposes, stacks are removed when empty.
Version : 4.1
name : the name of the stored stack. Stacks have names, much like variables do.
Result : empty on success, or if the stack doesn't exist. Returns ? on errors.
