issues with arguments fed to solver

[ttruneh]

Hi,

This looks like a really cool library ! I've been trying to get it up and running but have been having this error when arguments are fed to the solver:

TypeError: long() argument must be a string or a number, not 'ok_function'

I tried with my own examples and also ran some of the test cases e.g. radiation.py. Any advice as to what I'm doing wrong would be greatly appreciated!

I've been using the dev branch as had issues with the master branch as described previously.

Thanks a lot !

The full error for radiation.py below
