Segmentation fault (core dumped) error when using the (-m) option of pxseqgen

./pxseqgen -t your_tree.tre -o outfile.txt -m .33,.33,.33,.33,.33,2,.3,.3,.2,.5,.4

You are missing 2 substitution parameters in the call above. Nevertheless, an error should be returned instead of a segfault. Should be a very easy fix.
We might want to change how args are passed here. I think maybe they should be separated, say: -m for the background model, then -m2 for the model beginning at node 2, etc. But I'll fix this as it is now setup first.

Fixed with d934359. However, in implementing the check it is clear that this setup is very clunky. Should return to alter this at some point.
