Research, document and execute procedures to determine supported browser version.

[sscchan]

We need to understand and document how to determine the lowest browser setting
Related to #41 .

1. Identify how one can emulate specific versions of browser for testing.
2. Document procedures to emulate and check browser for compatibility.
3. Identify which Browser (IE, Firefox, Chrome, Safari, etc) we are supporting.
4. Identify which version the software supports.

Hi. Looking for issues to contribute to, and this seems potentially like a good one. A few questions:

• Do you expect the browser emulation to happen in CI?
• Do you use any existing browser testing framework at the moment?
• When considering "compatibility", what errors do you expect to arise? My naive guess is that there are two broad types:
  • Backend logic not being supported by the browser (non-UI related). The project seems to have some logic tests already, so some of these types of errors should be caught by those tests, if we run on an unsupported browser. (Though I also don't really know what it means to run the tests "on" a given browser, or if it's even possible.)
  • UI-related bugs due to unsupported/differently-supported features. I'm not sure how to test these at the moment, but I'm going to guess there are a million frameworks for doing UI testing of webapps (seems like Selenium is one of the de-facto frameworks?)

I'm definitely new to webapp dev, but hoping I can learn this stuff quick! Thanks!
