Adds Snapshot tests + CI (#332)

* Re-organizes and simplified project structure
Integrates Application sample project into same workspace as a new target
Adds snapshot testing infra + snapshots all Application cases

* Renames snapshot references directory

* Tweaks the sample project to update the status bar style appropriately

* Integrates Colors sample project into same workspace as a new target

* Deletes old examples. Don't need them anymore.

* Adds travis and codecov yml files, for setting up the CI

* Adds Dangerfile

* Wrong path!

* Ignores the entire project directory, so only the lib source is checked-in for codecov

* Adds codecov and travis badges in README

* Codecov path correction
