+# Mathematical Representation
+
+One of our goals is to have a complete mapping between the mathematical representation and the computational instantiation of our models, I want to work hard (and jointly) on the math notation and the computational objects.  In my experience, writing up the math often brings to mind important points that otherwise might be missed.
