Route fix

So, ignore the fact that it looks like shainerz is committing everything. Didn't change the name, oops. You can test route # (where # is a node you want the routing table from), and try it out. You have to pull libio and libcsp for all the code changes. Results at: https://gist.github.com/TheFlyingCouch/23c37cbf388f4246a575

@bryanyw 
using params[X] is an unclear way of showing what the meaning is behind the variable. I suggest doing something like:
uint8_t* params = (uint8_t*) &packet->data;
uint8_t  begin_index =  params[1]; // etc.
