Adding resistance as known dimension
Improved export of explicitInputs to Neuron
Minor update to handle multiple identical ids in OutputColumn

e.g.
<OutputFile id="of0" fileName="Pop0_v.dat">
   <OutputColumn id="v" quantity="Pop0[0]/v" />
   <OutputColumn id="v" quantity="Pop0[1]/v" />

is wrong, but now handled...
Minor change in naming of explicitInput in NEURON
Slightly more efficient saving to file in Neuron

Generating test script for working lems->nrn examples
Improved handling of ConditionalDerivedVariables in Neuron export
Initial support for export to Neuron of multicomp cells
