VESimHouseholds

Brian completed all the modules in the VESimHouseholds package. These modules include:
- CreateHouseholds - creates simulated households with persons by age and also non-institutional group quarters population
- PredictWorkers - predicts workers by age for each household (this is a new module which is needed for Liming's new multimodal travel models)
- AssignLifeCycle - assigns a life cycle category to each household (also required by Liming's models)
- PredictIncome - predicts annual household income. I reestimated this model from the original RSPM using the worker by age information which wasn't in the earlier model. This substantially improved the model fit.
- PredictHousing - predicts the housing type (single family, multifamily, group quarters) for each household.
All the preparation of the estimation data is handled by the CreateEstimationDatasets.R script.
Revisions pushed to the develop branch.
The package passes all the R tests but has a note that the package is larger than what CRAN accepts. That's due to the inclusion of the PUMS data used to estimate the models.
@Ben and others to test these modules using the new module testing capabilities offered by the visioneval package.
- In the 'tests' directory there are 3 folders:
  - 'defs' includes all the definition files required for the RVMPO test case
  - 'inputs' includes all the input files needed by the modules for the RVMPO test case
  - 'scripts' includes the test script. Running the script tests each module

Brian added functions for implementing linear models, binary logit models, and binary search.
- Writing these functions added some time, but they make module code more compact and understandable. In addition, they reduce a lot of redundant code in RSPM and should make transferal faster in the future.
Also modified the visioneval code to include units handling, as noted earlier.

Brian made some updates to the 'model_system_design.md' documentation and pushed those to the develop branch, but there is still more to do.

@Brian plans to complete the next package which handles all the land use and system supply attributes
@Brian complete documentation updates
@Everyone test and review Brian's additions
@Ben to test Brian's new modules, and merge to master if acceptable
