Removed update stress testing... to tempting to make me optimise earlier than needed.
Merge branch 'master' of https://github.com/grantus/jecs
Making a commit before I refactor the way that components / entities work (i.e. pretty much a rewrite). The current implementation requires casting of classes at run time and is pretty hideous.

Going to have a look at systems like "Ents" and see if I can create a leaner approach that uses Generics to support components rather than subclassing.
