Remove redundant files added in first commit

[gwaybio]

These lab1 files are the same as the files @sklasfeld added in a previous commit. Organizing the repository by lab, rather than by content, would maintain focus and I think is a better organization strategy.

This PR removes these redundant files I added previously

[sklasfeld]

Where did you get these files? Were they from Raju? If so, were they edited in anyway from Sarah's slides? Maybe they are more updated and should replace the slides I put in lab1/py27.

[gwaybio]

I downloaded them directly from Piazza. Does that mean they are more recent?

[sklasfeld]

yeah and it looks like they are also in Python2.7 so maybe you should just replace the files I put in the py27 directory.

[gwaybio]

alright, i believe I replaced the files - look ok to you @sklasfeld ?

[sklasfeld]

Sorry, I must have been looking at the wrong files. These are in python3. Therefore, they just need to go in a new directory 'lab1/py3'. Sorry for the confusion. The rest of the stuff from Piazza should also go in py3 folders. I wasn't sure if Raju already made the switch in the first lecture. I guess she did.

[gwaybio]

yeah it does look like the jupyter kernel is using python 3, but the code written will only execute in python 2 - e.g. print "what's", "up" will not work in python 3. Perhaps instead it would be best to revert the kernel instead of moving the file.

next year this will not be an issue if #4 is completed and the course is run on Github
