-- Sources-CopyRepositoryInfoTo.sql
/*
2014-12-11 Tom Holden ve3meo
2014-12-13 rev to copy repository info from AddressTable to sources using any
template (custom or builtin) having [Repository], [RepositoryLoc] and 
[RepositoryReference] fields. Copies only to empty fields for now.

Use the script Sources-UnifyAliases_RepositoryLoc.sql first to rename fields
that are aliases for the two above, commonly used in the built-in templates. 

This script copies the values from the AddressTable to 
the source fields.
AddressTable.Name ==> [Repository]
AddressTable.(City, State) ==> [RepositoryLoc]
