Overlay Quicktest Version 1

**Steps to use**
0. There are already some pre-existing quicktests, but to add a new one, make a quicktest & drop it into appropriate category directory under quicktest/new/list
1. Run grunt
2. `grunt lq` to update list_of_quicktests.json
2. go to http://localhost:9999/quicktests/new/newquicktest.html
3. Select Category, enter branch, expand to set svg width and height, then run.

**Hotkeys:**
- key 1 -> only show plots rendered with 1st branch
- key 2 -> only show plots rendered with 2nd branch
- key 3 -> show all plots overlaying rendered with 2 versions of plottable
- key 4 -> hide all

**Notes:**
- I would like to make the `grunt lq` task run periodically (once everyday or so)
- All quicktests in my directory do not explicitly set height or width anymore, and I pass in the svg itself instead of a div to append. This is because I could not find a way to override the dimensions in any other way.
- Plans for Version 2 include a sidebar that has all quicktests with interface to 'tick off' active quicktest to "hide" them. This way, people can view a single quicktest, search quicktest by names, filter quicktests etc.
- For now, I will continue to slowly migrate our existing quicktests until version 2
- More comments the better. Thanks
