Subject: Implemented `Iota` list constructor * recursively generates a list of
 `Count` elements starting at `Initial` and consecutively adding `Step` ** as
 most functionality of this library this function was modeled after its
 _Scheme_ equivalent `iota` ** it may be used as the foundation of a set of
 higher order list generators including e.g. `list-tabulate` * added
 appropriate test cases
