** The handling of if-then-else depends on the type of both the condition
15
** (i.e. is it concrete or is it symbolic) and the type of the data
16
** (i.e. is it a symbolic class that wraps a tree node, is it a structure
17
** containing them, etc.).  Some of the handling will work for any condition,
18
** any of the data, etc.  So far not difficult in a language with multiple
19
** dispatch including type variables.
20
**
21
** However, we are using C++, so there are a few extra hoops to jump
22
** through.  We declare ITEs as a struct containing a static function
23
** as then we can partially specialise templates of them.
24
** Specialisations of these are then given when appropriate types are
25
** introduced.  Care must be taken with these to ensure that we don't
26
** get ambigious template instantiations.
