    METRON-831: Add lambda expressions and rudimentary functional programming primitives to
Stellar

    ## Contributor Comments
    To enable use-cases where the user may want to do simple iteration, we can expose simple
functional primitives such as:
    * `MAP`
    * `REDUCE`
    * `FILTER`
    To fully support this, we will need lambda expressions as arguments to these functions.
    
    I also added a simple `LIST_ADD` to enable better testing of the functions and because
it was an easy-to-fill gap.
