should probably use a graphics library by default for some things? need to figure this out
statistics
create this since there are a ton of stats methods that will fall under this
some of the ml module methods/classes might be better suited under here?
calculus
expand this based on how calc topics are typically separated even in the calc sequence. Differential class is filled out to some degree
linear algebra
so far the Mtx class has a bunch of arithmetic methods that could be expanded upon and possibly need to be put in separate files given the platform specific code.
linear systems and eigenvalues need to be addressed
Update the headers for each module (linalg.hpp, ml.hpp, etc.)
