 Suppose you want to write a function to get the minimum of two integers.
 It's easy:


 Oh.. I see.
 Thank you everybody.


 And that's the first, more visible part of templates, a bit like
 generics in Java.
 Template are incomplete pieces of code with left-empty 'slots' which
 you can fill at compile-time to decide what code will be compiled.
 You can generate entire functions / class hierarchies or nicely
 crafted-for-your-need code / pre-computed-by-the-compiler code with
 templates.

OK... I won't play with templates for now, but please keep up the good work.
