Directory for index files between database object ID and sequence accession IDs.

File format:

geneObjectID	DBID:seqAcc;DBID:seqAcc;DBID:seqAcc; 

where multiple seqIDs are only added to reflect alternative
transcripts, not allelic variants.  Separate multiple sequence
accession numbers with a semicolon (';').

The first column is assumed to be of the form DBID:geneObjectID, where
DBID is stated or if not present the extension on the filename is
used.  For example, in the file gp2protein.sgd the first column:

SGD:S0000010	UniProtKB:P31373

At this time only NCBI and UniProtKB accessions are used for loading
the GOC database.
