| Provides a sequence for generating unique FID keys. Selects the max value of the fid column
then increments it with each successive call to getNext().
This may break if other tools are modifying the database at the same time. But this is a wider
issue that should be dealt with in a Geotools standard way. When that way is determined this
class can probably disappear. This is also part of the reason why this class is only package
visible, since this method of generating fids should not be used by other data sources.
