RAM_Toolkit: Create functionality for reading RAM deflection results

[jeanlucjackson]

Would be great to be able to pull deflection results for RAM bars, looks like the RAM API supports this functionality

Per conversation with Eric from Bentley, there is no DA method to get deflections directly. We will have to back these out from the load / moment diagrams per beam. This approach will also require a method to assess beam deflection interactions at connection points.
