====== Level variable template ======
Examples may be in you installed model already /models/<modelName/<versionNum>/views/subroutines/TemplateViews/levelORIntensiveVarProjection_v4.t

The template for this type of variable does 1 variable only and gives you several options on how to project it.

Currently those options include:
  * "saturated projection (default)"
  * "scurve to some percentage from last year of history"
  * "stepwise percent change various source options"
  * "specify and apply growthrate to last year of history"
  * "set constant (given or from reference year)"


If you have a non-standard projection time horizon (i.e. not beginning in the first year of simulation, and not based purely on a trend from history) then adjust 

<code>
local varHis[upperdims,timeseq]
local varBckGnd[upperdims,timeseq]
local varResult[upperdims,timeseq]
</code>

so that ''timeseq'' of ''varHis'' spans the time from which you might want to build the trend, and ''timeseq'' of ''varBckGnd'' and ''varResult'' spans the projection time.
