I'm going to have to come up with a way to ask which of several locations could be if there is significant overlap.
Right now, if more than 50% of scanned access points are recognized, then the location is considered "known"
However, if there are two locations that account for more than 50% of nearby access points, the AL's guessing becomes less accurate. This happens when two different locations are next to one another, separated by only a couple dozen feet or less.
For instance, in a Library, there may only be 60 access points. Lets say floor 1 can see 40 of those, and floor two can see 45 of them. There are certain places in that library where a scan reveals 30 access points, 16 of which are known to be on the 1st floor, 16 of which are known to be on the 2nd floor. 50% percent chance at guessing isn't good enough.
So, a dialog box needs to pop up with the two most likely choices.
