Expect that a detailed response cookie matches the supplied cookie name and hamcrest matcher (see {@link DetailedCookieMatcher}.
<p>
E.g. expect that the response of the GET request to "/something" contain cookie <tt>cookieName1=cookieValue1</tt>
<pre>
expectCookie("cookieName1", detailedCookie().value("cookieValue1").secured(true));
</pre>
</p>
<p/>
<p>
You can also expect several cookies:
<pre>
expectCookie("cookieName1", detailedCookie().value("cookieValue1").secured(true))
.expectCookie("cookieName2", detailedCookie().value("cookieValue2").secured(false));
</pre>
</p>

@param cookieName            The name of the expected cookie
@param detailedCookieMatcher The Hamcrest matcher that must conform to the cookie
@return The builder
