Snippet: Update a body's position and rotation

	/**
	* Updates the x and y properties of a body based on its
	* velocityX and velocityY, and, updates the rotation of
	* a body based on its rotationalVelocity.
	*
	* @param {Object} body: The body must be an Object
	* with x, y, rotation, velocityX, velocityY, and
	* rotationalVelocity properties.

Snippet: Method to update the diagonal velocity of a body

	/**
	* Updates the diagonal velocity properties of a body,
	* taking into account the body's current velocity
	* and applying any forces acting against the body
	* as acceleration on both the x and y axis.
	*
	* NOTE: This method DOES NOT update the position of
	* the body, it only updates its velocity.
	*
	* @param {Object} body: The body must be an Object
