Boost interval intersect documention error

[John Cummings <jcummings2@…>]

In the documentation for the boost interval library:

http://www.boost.org/doc/libs/1_44_0/libs/numeric/interval/doc/interval.htm

There are erroneous references to a non-existent "intersection" function.

Specifically, in the "Overview of the library, and usage" section at the end of the first paragraph and in the "Synopsis"" section after the comment /* set manipulation interval functions */ the function is incorrectly called intersection.

There is no such function by that name. Instead, the function is called intersect. The documentation later correctly names and describes the function in the "Operations and Functions" section.

The fallacious names need to be correct to avoid confusion.

(In [65118]) Use the right name for intersect. Fixes #4600.
