Moved files to test directory
Moved experimental mod and hoc files out of the way
Try selecting number of ions added by Poisson distribution rather than rounding
Experiment adding ions before update step
Rationalised so that multiple simulations should be possible
Removed redundant empty line
Remove some verbose comments
Finally got first test working

(i) Reorder update of states in _fixed_step_solve() so it occurs after
kappa steps
(ii) Have two kappa steps of 0.5dt each and add flux inbetween
Added getTime() method
Raise exception when NEURON and Kappa times mismatch
Created nrn-kappa script to run Neuron-Kappa
More universal handling of ss path and PYTHONPATH
Allow destruction of kappa objects
Added ability to specify units of SpatialKappa simulation
Make verbose reporting optional
Experimental code to allow Kappa code to run free of NEURON
Merge branch 'master' into kappa-independent-run
Added files in which I'll try using molar parameters
Changes to allow variables to work
Moved variable versions
