Add helper for console

[dupdob]

This proposal extends the scope of NFluent (somewhat).

Expected Behavior

One should be able to check the output to the Console with NFluent.
Such as

Console.Write("hello");
...
// this is not possible
Check.ThatConsole().IsEqualTo("hello");

Current Behavior

Nothing exists (within NFluent) to capture and check the output to the console.

Possible Solution

Using a mock is a solution, but it impacts design for simple code. NFluent should offer rely on the redirection features offered by the console.
Idea

using(var session = NFluent.NewConsoleSession())
{
  Console.Write("hello");
  Check.That(session.Output).IsEqualTo("hello");
}

Context

This idea occured to me while recording the TDD banking kata session. This idea probably needs refinements.
