Create plotAna.py

plotAna.py (plot Analysis): use to manually check a single distribution of a set of data. 
python plotAna.py
filename: insert.csv

**Accepts .csv Files**

Plot .csv 
Then "eyeball it", i.e. compare with standard distributions to find a possible match. 
Once one or more possible matches have been found, then you may use an MLE to choose which is the best fit for the set.
