5127	Incorrect result_of usage in transform_iterator	mimomorin@…	Dave Abrahams	"The documentation of `transform_iterator` says that 
`boost::result_of<UnaryFunction(Iterator::reference)>` is used to determine the functor return type. 
But this is incorrect; the correct one is `boost::result_of<const UnaryFunction(Iterator::reference)>`.

This is because
  1. The dereference operator of `transform_iterator` is a const member function.
  2. So, in the dereference operator, `UnaryFunction` is treated as a const object.

Accordingly, the code and the test need to be changed too. 
I will attach patches for the code, the test and the documentation. "	Patches	closed	Boost 1.47.0	iterator	Boost Development Trunk	Problem	fixed	transform_iterator
