Initial technologies set added for "assembly"

The micro segments JSON now includes specific technologies under each
fuel and end use for the commercial “assembly” building type.  A few
notes:

- In general, the technologies match all those broken out in the AEO
2014 micro tables by end use/fuel, with the exception of the “demand”
technologies in heating/cooling end use categories (more on “demand”
below).

- Heating/cooling end use technologies are broken into “supply”
(equipment) and “demand” (envelope components and internal gains).  The
latter will be based on the 1999 LBNL thermal load components study.

- MELs in the electricity end use are for now broken only into
“laundry” and “other MELs”, as commercial laundry appears multiple
times in the current P Tool measure set.

- The only “on site” electricity end use considered in AEO is for water
heating, which includes a solar water heating technology.  This
represents the case where solar water heating is used as a backup to an
electric water heater.

- We may need to add a census division level to this hierarchy, as the
AEO filters energy consumption directly for each technology by census
division, and it would likely be difficult to consider this filter as a
weight applied outside of the JSON.  However, this will add
significantly to the JSON length and complexity.  Ideally, we can write
a Python code to that mines the AEO micro tables to fill in each micro
segment consumption value (currently set to zero).
