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
Set initial Ca concentration lower and run compare_output
Output trace of Pi
Produce figures for paper with comparison of traces
Added getTime() method
Raise exception when NEURON and Kappa times mismatch
Updated file docs
Created nrn-kappa script to run Neuron-Kappa
Comment fix
Initial version of Refsim2 added
More universal handling of ss path and PYTHONPATH
Allow destruction of kappa objects
Testing framework rationalised
Animation code
Ability to change parameters of test_ca_pulse sims
