Document how CRSAuthorityFactory dynamically compose at run time
----------------------------------------------------------------

                 Key: GEOT-1265
                 URL: http://jira.codehaus.org/browse/GEOT-1265
             Project: GeoTools
          Issue Type: Task
          Components: doc
    Affects Versions: 2.4.M2
            Reporter: Martin Desruisseaux
            Priority: Minor


It is easy do get lost with the numerous indirection levels with {{AuthorityFactory}} in the referencing module. A document that explains what happens on the first call to {{CRS.decode(xxx)}} down to the SPI level would be very helpful. Some of the main classes involved are:

|| Class || purpose ||
| {{FactoryUsingSQL}} | for reading the EPSG database |
| {{BufferedAuthorityFactory}} | for caching |
| {{OrderedAxisAuthorityFactory}} | for changing axis order to (x,y) |
| {{AllAuthorityFactories}} | for querying all authorities (EPSG, AUTO2...) |
