Test sorting function: sortLiItemsByAlphabet by using own small list
Refactor one test and add new test to test sortLiItemsByCheckStatus
Test for sortLiItemsByCheckStatus to test it by using exisiting list of dimension
elements in setup component elements dialog
Add test to test sortLiItemsByObservationCount by using exisiting list of
dimension elements in setup component elements dialog

- yeah, you are right the test looks ugly, but seems working :)
Add tests for Model/CubeViz/Collection.ts; did a some refactoring
Nice ups test output: add points, ouput after a couple of tests are completed
