[stringtemplate-interest] 1, 2, and 3

[Ed MacDonald]

Thanks Terence.  It appears trunc wasn't implemented in the C# port of
3.0.1. (The method is defined but returns null).

FYI...
Here is where I had been reading about first, last, and rest with no mention
of trunc:
http://www.antlr.org/wiki/display/ST/Expressions

I also see reference to a "tail" function, but no description of what it
does other than to say "tail of a single-valued attribute yields the same as
first, the attribute value".

that is a damn good question. normally we do the first one different  
not the last.  OH. trunc(foo). I am adding to the cheat sheet. ooop.s
