Rerunnable code in matlab

[jpalmer]

Summary

At the moment, if you try and restart the code within matlab - for example running run_model twice, matlab will segfault.

The segfault is caused by an issue with the arguments to the first call but this isn't the real problem - we need a way to call the init functions again.

The problem is that we only have a single entry point from matlab which does make things a little more difficult.

detail

the code in the run_model script
does something like:

[V,outputs]=conductance('dummy',output);

this is because we don't know how big the voltage array needs to be
(on the matlab side).

So then in the C code, since the setup has been called, it tries to
use dummy as an input voltage matrix which obviously fails.

My suggestion: in mexfunction in src/conductance.c add some check on
the input arguments and then use that to set setup_done to 0 -
basically you want to do:

if input[0]=='dummy' then setup_done=0

obviously, not quite this simple, but that is the rough idea
