[Biojava-l] extra seqDB things to add

Dear all,

It is great to see the seq.db package up and running. I think that it
needs a couple more things to be the basis for realy useful work:

CachingSequenceDB
- wraps a parent seqDB
- ensures that sequences are fetched once only
- should use weak references (or whatever it is) to be memory-sensitive

FileIndexerSequenceDB
- indexes a list of files
- uses a normal seq.io object to specify the format
- creates a file bla.index with the indexing info
- possibly auto-manages updates using file dates/times

Any thoughts?

Matthew
