Test

The following tests focus on attempting to generate some math, containers, and the memory module of zpl.

Not all the files are written how I would practically use the library, the containers for example would be better on in c++ as templates, since the templates they generate are trivial symbols to inspect or debug.

An example of a non-trivial generation is a container for elements with SOA or AOS policy for layout. (If a unified element syntax is desired)
