Adding PM diagram plotter, DCR calculator, table in calc report

[janderson4]

Added a plotter for axial-moment interaction where the factored load is specified as Mx, my, P, and a function is called that interpolates between the points of the PMM diagram to create a 2d cut at the right lambda.

Added a method for finding DCRs that works by searching for a point on the capacity surface with the same lambda and eccentricity as the load point and returning a ratio between one of the demand values and the capacity value. The type of this DCR is “PM Vector.”

Updated the algorithm for searching for points for the PMM diagram, the new one has better convergence.

Added a table to the try_axis_document method for showing the contributions from each bar.
