testcommit
+ Added new sensor reading class to parse kml files.
+ Added code to loaded arterial sensors in kmz file.
+ Added database column road_type to orm_sensor to specify the kind of road the sensor is on

* Extracted the srid values in the modified files to a constant value at the top of each file. The long term plan is to move these constants into a configuration file.

 -Additional testing needs to be done to verify the changes.
 -Need to ask if the current data is sufficient.
Altered path in file to match other files.
