Finally finished first phase of trussbid.

Thus verily it came to pass that I did finally find time to do some formulas for truss pricing. It has been said that trusses are stupid and it was so.

After using spreadsheets and truss software and forcing them to be friends I have finished the first part of my truss bidding theory. Like me it is ugly and crude but gets the job done. Thank you ZZ for the joist tool and Heber for helping me tickle the formulas a little bit.
