## Pseudo-code ##
#add current selected connection to curList, if signal strength is too low it gets cut off instead
#show all connections with whom user is connected
#Pick highest value loc in curList and triangulate location of user by reducing the x and y cordinates of user by that of the other location(s)
#Extra: signal strength adjusts the location further by pushing it to either side.
