Home page and prints!

# Changes

## index.html
* re-created the homepage counter image in static css. Will work on function to "update" when we have live data
* removed commas from fake data as it was breaking the sort functions. live data will not have commas anyway.
* removed counter.js from scripts list

---
## compare-groups-view.js
* made it so both the groupsToCompare and groupsToAdd array are wiped upon view initiation
* added a print function which will hide all other elements except the table and restore them after printing/cancelling

---
## group-view.js
* changed which variable was being passed into the query on initialize. Will now use the groupID instead of groupName. Page still renders details accurately, however the url is now unique as the groupID is already unique.

---
## user-nav.js 
* added a text parser to grab the user/groupname and capitalize the first letter of each word. If the name contains a ".", the entire string is capitalized. (i.e. "u.h.f." -> "U.H.F.")

---
## main.scss
* updated styles for the counter, print function and small tweaks
