Draw a line between 2 Choosen POI and also give orientation

[belguinha]

For example. I add POI labeled StationA, in a checkbox I choose connect to other POI option. A drop&search box to locate the StationB POI is unlocked, select the StationB that I want and the system draws a direct line from stationA to stationB, automatic distance between 2 points is added, aslo bearing in degress if possible.
