Member Code Checks

**Describe the solution you'd like**
I know it's a lot of work to program in member capacities, but it would be nice to have some method of calculating and comparing to code allowables. Most users of this package will probably be more interested in obtaining code checks than anything else.

**Additional context**
Obviously it's a big "add-on", somewhat removed from the core of the FEA solver. But it seems it would make a huge difference in usability for the typical end-user to include.

No files, tests, or entry points are mentioned. Start by surveying the VBA FEA solver and defining the design-code and member-check scope with maintainers. Done should be demonstrated by calculating and comparing code allowables, as requested.
