Add error message when user importing raster and it does not have 100x100 resolution.
Add message in README outlining specifications of raster that can be imported
Added requirements that pgpass is needed either by env var or pgpass.conf file
Updated oracle pg connection to update user mapping with oracle keyring password every time. This should help when BCGW password has changed. The user still had to update the keyring.
gr_skey table now has integer primary key rather than double precision
removed hard coded 'prov_data' database setting pg conn set up
modified raster table comments to remove the relational table as it doesn't exist
