do not use popt

Making your code depend on platform-dependent libraries such as popt, which is a terrible piece of incompatible code makes your code dirty. Please fix.

Thanks for pointing it out - I've been meaning to change this for some time now. Do you have any suggestions for a platform independent command line parser library?

Use TCLAP! It's pretty straightforward, and header only meaning you can just track it here in your repo :)
