Detailed Description

template<class BinaryFunction, class UnaryFunction1, class UnaryFunction2>
class Trig::binary_compose< BinaryFunction, UnaryFunction1, UnaryFunction2 >

Function adaptor for combining function objects.

I got this function adaptor from the STL documentation, because it doesn't seem to be present in recent versions of GCC.

What it does is that if you call it with a binary function "bfn( X, Y )", and two unary functions "x1( X )" and "x2( X )", then internally it will evaluate as

bfn( x1( X ), x2( X ) )

The concept may be a bit tricky, but have a look at the STL documentation...

This class is not actually used by the code anymore, but I didn't just want to throw it out, as it might come handy later on.
