I've tried building this with both visual studio and and g++. I'll link my error messages here, they're basically the same both places though.

The weirdest thing is that visual studio finds and recognizes the header file because I don't get any errors before build on the methods not being recognized. It's only when I go to build (and linking happens) that I get errors. I feel like I must be missing something small but I don't know what it is.
