added my solution to the dinodex problem

Here it is.

You could just require this in IRB and call ```parse_dino_csv```. It expects the dino csv to be in the same dir. 
`to_s` would be a generally better usage here. `puts` makes this hard to use outside of a REPL. Also, this method is repetitive, find a way not to have to write each line of this thing.
