[fdo-internals] Request review of RFC 28 - Add Start/End ExpressionFunctions

[Robert Fortin]

Jason,

The use case: presents the ordinates of a point geometry as attribute in a data table.  This feature will help us achieve that.
You could also think it can be used to display the coordinate as labels as part of the symbology of a feature.
Or you could use the StartZ to show the elevation of a point or apply a theme on it.
All these can't be done easily directly using the geometry attribute.

Not sure what the use case is for these functions, but the implementation seems reasonable to me.  I'm glad that the name of the functions were changed from the initial take :)

I'd like to ask for a review of RFC 28 ( http://trac.osgeo.org/fdo/wiki/FDORfc28 ) which adds some new geometry-based functions to return start and end ordinates.
