Rewrite in Progress.

Specifically written for people who have a difficult time 
figuring out their meds. It's easy for family or a healthcare
professional to update and print when changes are made.

It parses a medicine descriptor string used to describe most 
forms of medication. (Universal Medicine Descriptor Language). 
only caviat is some meds have weird shapes. A solution is to 
allow the medication descriptor to include a link to a bitmap.

Milestones
[x] parse csv
[x] draw time, number, medication name, dose
[x] parse UMDL as vector
[ ] parse IMGUR 5 or 7 digit code when no UMDL is present
[ ] write up formalized UMDL
