Added a data cleaning report to cleanData, to show how many rows and individuals were lost at each step.
Added interaction locations to getEdges and getRoostEdges, with a parameter getLocs (default FALSE) for getEdges, getFeedingEdges, getRoostEdges, and getFlightEdges. Only makes a difference for return = "edges" or return = "both". Can't really return a location for SRI--by definition it's multiple locations.
