14 simulation names

[zorian15]

Description

Add file name customization to antigen to make experimenting a little easier.

This is just a barebones start so far, as I just tack on a few parameters (mutation rate, phenotype space, and CI strength) to file names. This week I'd like to add some more structure to file saves -- or at least add a parameter in the yaml file that will create a directory to output files, and maybe a prefix/suffix field to take on run numbers. But will discuss more with @thienktran to see what she thinks!

Closes #14

Tests

Please describe the tests added to verify correct behavior.
