Make intel compiler happy

By fixing a narrow conversion
Fixes: #243

I guess this works for now, but the enum's type should probably be made explicit at some point in the future. I'll make a ticket, but we don't need to change it now.

As an alternative to casting, it seems that the error could be fixed adding unsigned int to the enum definition here, as in:

enum CellFamily : unsigned int { NEURON = 0, GLIA = 1 };

Is this what you suggest?

Yeah, that's what I mentioned in #247 (comment)

It's a breaking ABI change though, so if we're going to do it properly, we need to do it all at once, and version the ABI.
