Detailed Description

A special class that converts a Qt signal into a std::function call.

Usage:

   \code{.cpp}

   std::function<void ()> destinationFunctionCall(std::bind(someNiceFunc, firstParam, secondParam));
   SignalToFunctionProxy proxy(destinationFunctionCall);
   connect(srcObject, SIGNAL(sigSomethingChanged()), &proxy, SLOT(start()));

   \endcode

Now every time sigSomethingChanged() is emitted, someNiceFunc is called. std::bind allows us to call any method of any class without changing signature of the class or creating special wrappers.
