Merge branch 'master' into developer
mix of change to developer and lcms

Unfortunately I didn't check in my developer changes before I started working on debug info in the regressions and pdfs.  So this push includes both.

At any rate, this is a basically working developer model.

As well as version of yamlmodelrunner which returns debug information for the regressions and simulations.

not too much different but just enough - doing square footage instead of units causes some issues - also added random building type selection - other than that this is looking pretty good
adding simulations dir

Merge pull request #40 from synthicity/developer

the basic developer is working in bayarea and semcog
