Tests to components.

[vish288]

• Decide on a framework to test the components being written
• Use snapshots to drive consistency
• add readme file for each of the component & also update wiki on each of the docs.
• Write Js Docs enabled comments on each of the component and generate Js Docs.
• Versioning of releases and wiki to document.
• Determine a coverage percentage and use codecov.io/coveralls.io bot to map and gate the PRs.
