VE-State/VE-Reports Update (2020-05-13)

Installer snapshot from VE-State / VE-Reports update from Oregon DOT.
2020-04-24: No change to code base; changed installer to remove unnecessary development artifacts
2020-04-20: Added short tutorial script to VEReports package.
2020-04-14: Added replacement for VeHouseholdVehicles called VEHouseholdVehiclesWithAdj. The revised code allows users to specify target ratios of drivers to persons by age group (rather than adjustment factors as previously) and also allows user specification of target ratios of vehicles per driver.
2020-05-13: Tweaked visioneval itself to support some snazzy scripting using summarizeDatasets. See the PBOT-Measures-Script.R and PM-Spec.R files, which you could probably run on the standard VERSPM sample data.
