Add support for fan powered box
SDD: Add report variables
SDD: Translate CoolingTowerVariableSpeed

This is preliminary, because there are still many details to translate.
SDD: Add support for heating only systems

Translate new AirSys:Type "HV".
Merge remote-tracking branch 'origin/develop' into sdd
Implement AirLoopHVAC::mixedAirNode()

This method was defined in the header but never implemented.
SDD: Support Fan:Pos on AirLoopHVAC

Now you can have a blow through or draw through fan position.  The
Fan:Pos element controls this, where previously the fan position was
dependent only on the fan element position in the SDD xml file.  Also
the controls (setpoint managers) are now arranged appropriately for blow
through control.
SDD: Translate FluidSys:TempCtrl = WetBulbReset

WetBulbReset will now give you a SetpointManagerFollowOutdoorAir.
SDD: Improve name of ControllerMechanicalVentilation
SDD: Translate CoilHeatingDXSingleSpeed name
SDD: Allow no design day run

Only run design days if Proj:SimDsgnDays = 1 or Proj:HVACAutoSizing = 1
SDD: Enable master override to run design days

SDD translator has a master override that will force autosize regardless
of what is in the SDD file.  This change forces design day runs of the
master override is on.
SDD: Update AirSys component add method

Recent addition of blow through fan option caused some controllers to
reference supply outlet node instead of the immediate outlet node for
sensor node.  This change adjust the component add methodology to
correct the problem.
SDD: Create partial update to fan coils

This is an incomplete update to support various fan coil operation
schemes.

SDD: Improve translation of four pipe fan coil
SDD: Improve four pipe fan coil translation

This is really an improvement of the components within the fan coil.
For FanOnOff translate fan power curve.  For heating and cooling water
coils, translate the design inlet / outlet temperatures.

In the case of water coils, this change will impact all coils, not just
those on a ZnSys.  Previously design inlet / outlet temperatures where
completely defaulted, now they are based on appropriate properties in
the containing ZnSys or AirSys.
SDD: Adjust AirSys:ClgCtrl

Now single zone systems (those that should use
SetpointManagerSingleZoneReheat) are defind by AirSys:ClgCtrl =
NoSATControl.  Previously these systems were defined using Fixed ClgCtrl
and system type SZAC or SZHP.  In short now the SDD defines exactly what
type of control (setpoint manager) you get instead of expert logic based
on system type.  Except for the exception SZVAV where control logic is
still based on the system type flag.

SDD: Add report variable requests
