Suggestion: Expose functionality to parse String to Header

[domdeger]

I am so thankful for your library. I have one suggestion to make, it would be great if there were a easy usable functionality to parse just the Header from a received Message. Currently i have to use the Parse-Method of an DummyMid I derived from Mid-Baseclass in order to achieve this.

I need this since I am using unit tests really extensively to cover my application. In my mocking class i like to atleast parse the header in order to find the correct response for the unit test.
