incomingR geocoding updated to fetch records and return dataset of geocoded records.  That dataset is then used to update the original edn.geo.  However, this does not work if addressid and aliendID are not unique.  need to work of deduplication function...
completed code on incoming R to allow for updating records.  also modified geocoding loop to limit to the number of records being geocode (~2000), instead of all the records that need to be geocoded (`300,000). The loop runs much faster with the smaller dataset.
adding several files not previously included.

incomingR, plot.routes, and gGeoCode updated
