HTML pages for single lock loss events

We need a nicer way of displaying the data that gets generated. One step is to have some basic bootstrap-style HTML pages that gobble up plots and display them in a nice way.

I had two approaches to have us get started on this. @jameson.rollins, let me know which you would prefer:

1. Use glue's markup module for HTML generation. I have used this in the past for generating simple pages. It seems hard to scale beyond something simple, but doesn't introduce any new packages.

2. Use jinja2 for HTML templating. This is a bit more feature-rich and I've also used this in the past for making nice HTML pages. It introduces an extra dependency, but is also a dependency of sphinx, which is commonly used for automatic code documentation in python. Anywhere where sphinx is already installed (CIT, but not LHO/LLO) has jinja2 installed system-wide.
