Work in progress

[Martin Desruisseaux]

Thanks all for the votes on the "profiles" group of modules. I will 
commit it probably next week.

For now I started to port some referencing classes, beginning with Well 
Known Text (WKT) parsing and formatting. One issue is that different 
organizations have different interpretations of the standard. 
Consequently I'm proposing a Convention enumeration [1] for specifying 
which "standard flavour" to use. Other classes and enumerations 
submitted in this "org.apache.sis.io.wkt" package are for specifying the 
symbols and colours (for X3.64 enabled terminal) to use. The classes 
performing the real work would arrive probably next week.
