Edits for April 8th, 2014

1. Grammatical edit to definition of variable 'whitemom'.

2. Added the variable 'mature' to table on the first page. (This caused the first page to become two pages, which blurred into the figures of bin var vs. cont var)

3. Added description of the variable 'mature' to the same paragraph as the description of 'premie' and 'lowbirthweight'.

4. Added continuous variable vs. binary variable plot for variable 'mature'.

5. Added xlabels to cont. var vs. bin var plots as well as removed ylabels for clarity.

6. What do ya'll think of GESTATION PERIOD rather than weeks? I thought I'd try it out and see if it makes sense.
