Added tests for measurement view to check date parsing (forwards and backwards).
Ignoring testdata db file.
Added unit tests for measurement/reading views. Hacked together a factor for angle values. This can later be removed.

Looks good for now, need to remove angle factor and consider Date.UTC for base time for offsets.
