[BLDG-SIM] DOE2.1E Chiller performance

[Fred Porter <fporter@xxxxxxxxxxxxxx>]

Common problem. You are using a recent version of DOE2 based on an 
implementation by Jeff Hirsch, but using documentation and keywords from 
older versions. All CHW & HW characteristics are now declared in Systems 
Plant Assignment, not Plant Plant Parameters, CW stuff is still in PLANT.

Correct documentation is available from DOE2.com. The v110 bdl 
supplement or something like that.

However, for plant analysis at this level of detail, I would highly 
recommend DOE2.2, instead of DOE2.1.
