Mocking of header method

[hellboy81]

I'm trying to use ``mock-req`

Initialization in Unit tests:

MockReq = require('mock-req'),
var req = new MockReq();
// req.header = function(){} // with this line it does not work also

Testable code:

if (req.header('content-range')) {

I'm getting message:

TypeError: Object #<MockIncomingMessage> has no method 'header'

According to http://nodejs.org/api/http.html#http_http_incomingmessage there is no method 'header'.
