def lookUpBaseByDBID( entityType, dbID, callback ):
This script function looks up the specified base entry in the database, and calls the result handler with its mailbox.
Parameters: entityType  entityType is a string that specifies the type of the entity to look up.
dbID  Specifies the database ID of the entity to look up.
callback  callback is a callable object (e.g. a function) that takes one argument. If the lookup is successful, the callback is called with the base mailbox, if it is unsuccessful because the specified entry is not currently checked out, it is called with the value True, and if it is unsuccessful for any other reason (e.g. specified entry does not exist) then it is called with the value False.
