TypeError when attempting to run top.py on macos

[Adrian Bradd]

Running macos 10.12 and Python 3.6.1 :: Anaconda 4.4.0 (x86_64). When running 'python top.py' I get a TypeError from os.path.isdir likely because of a malformed input. This occurs on both master and develop. Backtrace is below:

This is likely because you'd run YCircuit there before and it had created a .config file for a previous version. As I add new keys to the .config file, I haven't yet implemented a way to use the existing ones and add the missing ones - it just crashes by default. Try deleting the .config file and running it again (you will lose your config settings though, if you'd rather not lose them, make a backup and copy over the values via a diff).

[Adrian Bradd]

That fixed it.

As of the latest update, this error should not show up at all. The program now assumes default values for missing entries unless they are explicitly changed from the options menu.
