(ABM-269) further cleaning and refactoring of Emfac2011 codes; initial
commit of two Emfac2011 properties
(ABM-269) Emfac package overhaul working.
(ABM-269) 
1)	Reorganized Emfac folder structure to blend in with ABM main folder
structure.
2)	Merged EMFAC properties (base and model properties) as part of main
sandag_abm.properties.
3)	Made package compatible with new DB schema
4)	Emfac is included as part of ABM build, simplified user interaction.
5)	Include truck modes as mutable type so truck VMT is updated in
Emfac2011 using modeled data.
6)	Refactored/optimized/added codes.  Removed reading from CSV files,
instead reading directly from DB.  Speed up some codes, e.g., trips
table is only to compute intrazonal VMT, it doesn’t need to loop through
all OD pairs, only need to loop through a small data set by applying
query orgin=destination.
7)	Run time reduced to <7 min (without generating Aquavis tables, 3.5
min)
8)	Emfac can handle future years later than 2035 by assuming: if
year>2035, then use year 2035 inventory file.
