      Description

      An extension to allowing dafilesrv to read indexes remotely would be to allow it to project which fields are required.

      This would require changes to the code generator to generate an RtlRecord structure for the fields in the index that are actually used - so that an efficient mapping can be created to project the fields.

      It should probably also cause a new transform() function to be created, which can be applied directly to the serialized extract. There are probably a reasonable number of situations where this second transform would do nothing, so could be replaced with a clone. These cases should be spotted and optimized.
