Sketch code for Conversion: Lat-Lon to cartesian

Latitude-Longitude pairs are unit-incompatible with the distance
field for each sensor packet (which is given in meters).  To resolve
this discrepancy, when attempting triangulation, all packets must
be assigned a X,Y coordinate pairing (based in 'meters').  Initial
outline of this process is laid out in the committed code
