 * 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.

 * 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()>
