[geotk] Changes in import statements of FactoryException and Unit

[Martin Desruisseaux]

Hello all

We are preparing the final release of GeoAPI 3.0, applying the changes voted 
during the last OGC meeting (http://jira.codehaus.org/browse/GEO-188 except the 
discontinuation of java.util.Date). Those changes are minors, except for two 
changes in import statements:

  * javax.measure.unit will need to be renamed to org.unitsofmeasure.
    This change can not be avoided.

  * Factory, FactoryException and NoSuchIdentifierException are moving
    from 'referencing' to 'util' package.

Users can update their code base by executing the Ant script below:

    http://www.geoapi.org/changes/3_00.xml

Only the move of Factory and related classes is applied today. The renaming of 
Unit package will be applied later.

This affect only those who use the GeoAPI or Geotk snapshots. Those who use the 
stable releases are not affected until the next release is performed.

After the renaming of Unit dependency is applied, GeoAPI 3.0 will be submitted 
for the final electronic vote by the OGC Technical Committee.

	Regards,
