Documentation Typo

http://microsoft.github.io/cpprestsdk/classpplx_1_1task.html

As listed it states:

pplx::task< _ReturnType > Class Template Reference

However, the < _ReturnType > is described as "_ResultType" as written in the description as follows:

The Parallel Patterns Library (PPL) task class. A task object represents work that can be executed asynchronously, and concurrently with other tasks and parallel work produced by parallel algorithms in the Concurrency Runtime. It produces a result of type _ResultType

Is this a typo?
