+	Class: BlockDefinition
+	An object representing a set of actions to perform independently from the rest of the script. Blocks are basically just
+	lists of statements to execute which also contain some local variables and methods. Note that since functions are local to a block,
+	it is possible to have a function definition inside of any type of block (such as in an if statement or another function),
+	and not just in the global scope as in many languages.

+	Proc: SetVar
+	Defines a permanent variable. The variable will not be deleted when it goes out of scope.
+
+	Notes:
+	Since all pre-existing temporary variables are deleted, it is not generally desirable to use this proc after the interpreter has been instantiated.
+	Instead, use <n_Interpreter.SetVar()>.
+
+	See Also:
+	- <n_Interpreter.SetVar()>
