Description
Right now, in order to check for null we have to use:
#if ((! $var) && ("$!var" == ""))
which is painful when you have lots of checks to do in several places.
It would be nice either to have better null check support in velocity core or to bundle to NullTool in Velocity Tools:
http://wiki.apache.org/velocity/NullTool
I checked the user guide and googled around and couldn't find any simple way to check for null except using an undefined variable which I find way too magical and dangerous (what if someone defines that variable in the context).
