[udig-users] Celebrate PI day with new functions for reshape operation

[Jody Garnett <jgarnett@xxxxxxxxxxxxxxx>]

I have added a couple of "no argument" functions:
- ID() - returns the current feature ID
- PI() - 3.14159...., useful when working with sin, cos, etc...

How can you try this out? Perhaps you can download a nightly build - I 
am not sure if it picks up changes I have made to the GeoTools library 
or not, suppose we can find out tomorrow.
