Swap in rendering framework such as Angular template

[vrisk]

The html could be more efficient and cleaner if you used an AngularJS template in place of the original html. This is probably a fairly significant refactoring task, but would help the maintainability longer term.

The interface currently employs VanillaJS, a lightweight JS framework for rendering front end of web apps. Switching to Angular would require extensive refactoring since much of the dynamic code is currently being generated at the back end by NodeJS. This enhancement would definitely make the code more modular and maintainable, hence marked as a long-term goal for Anterius
