calc_trend function cannot handle a historical observation being None #11

Closed gjr80 closed 6 years ago

gjr80 commented 6 years ago

When calculating a trend value if the historical record obtained from the archive contains the observation field concerened and it's value is None then the code will fail with a TypeError. The fix is to expand an exisiting conditional check to detect the None value and return None.
