TSdates.TSdates returns information about the start and 
end of each series in serIDs. con is a database connection as returned by
dbConnect.  TSdates also provides simple way to query a regularly 
used database. The connection can be set in options
using options(TSconnection=con) and then only the series identifiers 
need to be specified in calls to TSdates.start, tfstart, end, and tfend extract start and end dates from
the object returned by TSdates.
