The test folder has two types of tests - some are proper unit-tests,
while others are quick and dirty executables. These executables are
always commented out so that the only one that finally runs due to the
main is the program created by TestRunner.cpp

I use this setup mainly because this is one of the quickest ways to keep
writing new code to produce an executable using Eclipse. Will probably
change this over the course of a few days, but for now this works well
for me. :)
