directory itself. Now can be installed via pip.

- Adding some documentation (docstrings)
- Converting random print statements into log messages using the logger
modules.
- Also moved the LICENSE to the proper place in the directory hierarchy
so that it shows up on github.

locations.

- Spec2017Bench now overrides the SPEC17_ROOT variable in the makefile,
allowing spec to now build properly.
- Added a bit more documentation.

- It wasn't actually an issue with the signal handler like I thought. It
was actually that I wasn't catching a GDB error from parsing the "show
language" command. It is now fixed.
- Some other minor tweaks.

Before we can merge 0.6, we need to do the following things:
- Get single simulate and parallel simulate working again (currently I
need to test after rebuilding gem5).
- Get keyframes fully implemented, which will dramatically increase
usability.

- Parallel still terminates early for some reason

- Need to clean up the stdout/stderr interweaving.
- Should also clean up some of the logging infra

Tips and tricks:
- stdout/stderr should be in text mode (at least for python2.7, I think)
- need to seek to 0 to print
- can't use io.StringIO because python expects fileno() to be
implemented on stdout/stderr
