Creating an explosionForce method for 2D physics objects

For 3D games, the Rigidbody component has a useful method called AddExlosionForce(...) that will cause an object to look as if it's exploded from a given position. However, there is no such method for Rigidbody2D components. In this recipe, we'll write an extension method for the Rigidbody2D class so that we can add an explosionForce method for 2D objects.

Thanks to Swamy for posting the code for the Rigidbody2D extension class's explosion force on Unity Forum (Nov 21, 2013), which this recipe is based on:
