Tide Indicator Pi Project #9 - Calculation of Current Tide Completed (No bugs)

The last version I posted, v2.2, turned out not to work for all tide states, due to some maths errors. These have all been fixed and the code seems to work well.

I've think I've finally got the hang of updating to github, so here's the latest code:

tideproject/tidenow3.0.py

This is the output:

(datetime.datetime(2016, 1, 14, 21, 34, 13, 517280), u'10.5')
(datetime.datetime(2016, 1, 15, 4, 9, 13, 518325), u'1.9')
Tide is currently:  falling
Tidal Range =  -8.6
Current Tide :  9.55460304533


Next job is to have it running continuously and outputting to this webpage.
