adding html unit, plus an example. renmaing classes using consitent schema in prep for new controller
noticed a small typo in the CLI
adjusting scope of methods in controller for clarity
created htmlunit controller - updated exception handling - tests pass and code compiles
created htmlunit controller - updated exception handling - works except for JS-loaded elements
adding a TODO to remind me where I am
removing selenium controller - no longer needed
removing selenium from build - no longer needed
Merge branch 'feature/html-unit' into develop
