Standard Structural Joints

The Joints catalog should be structured so that all joints of a given generic type are stored beneath the same section, for example, cleats, endplates, baseplates. Within each section the joints should be broken down into categories relating to the types of sections to which the joint can be connected, for example, I‑I, I‑Chan, I‑L. The generic types of the sections should be stored against Ownconn and Attconn attributes.
