Trait FunctionFrameEnvironment 

pub trait FunctionFrameEnvironment {
    // Required methods
    fn push_fn_frame(&mut self);
    fn pop_fn_frame(&mut self);
    fn is_fn_running(&self) -> bool;
}

An interface for tracking the current stack of functions being executed.

Denote that a function has completed and is no longer executing.

fn is_fn_running(&self) -> bool

Determines if there is at least one function being currently executed.
