Bugs

Missing comma in array input leads to a segmentation fault.

If one uses arrays within a call to the register_model function, e.g.

() = register_model("blah",["par1","par2"...],...)

and one leaves a comma out of an array, there is not an immediate indication of an error, but rather the session suffers a slow death ending in a randomly-placed segmentation fault.
