Simulator change log

02-28-17 College Park and Denver virtual reACT houses go online.
03-01-17 Heat transfer model in wallGeom.exWallHeatXfer() was improved to include thermal conduction through external-wall windows.
03-17-17 Minor format and content changes to SD2017PVmodules.xml.
04-03-17 Major updates to the structure of the PV module and related classes contained in PVperformance.py. A new module houseDesignParam.py was created to contain reACT and LEAFHouse design elements. predictDay.py was modified to accept the changes.
05-03-17 The first phase of virtual LEAFHouse went on line.
05-26-17 Major update to the directory sturcture of the software project to facilitate future expansion; virtual/actual LEAFHouse power production comparison goes online.
07-05-17 Added Schlick's approximation to solarIrradiance.projectIrrad to model sunrise/set conditions; LEAFHouse Neurio power consumption readings and plotting added; new hvac class.
07-14-17 Simplified ERV thermal/electrical power and infiltration models added to hvac class.
07-16-17 Floor/environment heat transfer added to both reACT and LEAFHouse; updated LEAFHouse external dimensions.
07-19-17 Modifications to irradDay.project() accounting for shading of direct irradiance ED by trees and other objects after sunrise/before sunset.
07-26-17 Courtyard energy and house CO2 balances added.
08-11-17 Improved infiltration model; greenwall CO2 consumption model element added.
08-15-17 Removal of a number of coding redundancies including the elimination of dailySimularor.py, incorporating the current exisiting virtual reACT and LEAFHouse information as an alternative contructor function in the predictDay class.
