Allow routes to have laps/loops
In actual use cases it was noted that some users were creating routes with multiple laps by manually creating the loops by clicking around multiple times.
Should provide two features:
1) Close a loop: Connects the last existing point with the first.
2) Then when this is activated(? may not want to limit to this), allow user to enter the NUMBER of laps of the loop, automatically figuring out the actual distance.
