[CCF] Major back-end upgrade on VOACAP Online for Ham Radio

[Jari Perkiömäki]

A few weeks ago, VOACAP Online for Ham Radio, 
https://www.voacap.com/hf/, was moved to a new web platform, and this 
change forced me to re-factor a majority of the code in the back-end. I 
have now completed this task and am pleased to inform that the coverage 
area maps and point-to-point prediction graphs are now much cleaner & 
neater than before, using a different mapping library in Python 3. In 
addition, most of the codebase has been optimized and hopefully is more 
robust than ever. Especially the Propagation Planner, the propagation 
planning tool for HF contests (e.g. CQWW) & DXpeditions, should now be 
faster and also, as a bonus, offers the predicted values as CSV files 
for more detailed analysis.

required, no irritating tracking on the site by Google Analytics, no ads
