[udig-devel] Simple Filter editor for UDIG

[Jesse Eichar <jeichar@xxxxxxxxxxxxxxx>]

A filter editor needs to be created for UDIG.  All we need at the moment 
is implementation for the following methods:

ProjectFactoryImpl.convertFilterToString(EDataType, Object)
and
ProjectFactoryImpl.createFilterFromString(EDataType eDataType, String 
initialValue)

This will allow the filters to be saved and loaded if desired and edited 
in the properties view.

Oh, the methods should ensure that no exceptions are thrown.  This 
causes some poor behaviour if someone types in the wrong string.
