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:

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

local varHis[upperdims,timeseq]
local varBckGnd[upperdims,timeseq]
local varResult[upperdims,timeseq]

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.
