Update scrip to better obtain console dimensions

[scottfurry]

Recently moved from a Linux to FreeBSD system. Executing script resulted in "recursion" errors pointing to usage of columns variable. Eventually came to realize that columns and lines variables were not being properly populated during execution.

After review of stty man page for FreeBSD, I was able to come up with a more robust method of obtaining terminal sizing.

Review of Debian stty man page leads me to believe that this change should work there as well.

Solution is to explictly call for terminal sizing from stty via an attribute. This boils down to change of one line. Change works locally.

This effort may also close #6 but should be tested. I was not able to locate a conical reference for stty for MacOS. Only reference I could find is here
