Panels GridTemplateRows Property

(Almost) directly specifies the CSS grid-template-rows property. Specified as a vector of vectors rather than a space delimited simple character vector. For example:

   g.GridTemplateRows←'1fr' '2fr' 'auto' 

If empty (the default), and if AutoSize or AutoSizeRows is 1, then this property is effectivley set to n⍴⊂'auto', where n is the number of rows.

If empty, and AutoSize and AutoSizeRows are both 0, then this property is based on the proportions implied by the [GridTemplatAreas] property. For example if:

      g.GridTemplateAreas←[ 
                            0 0 0 0
                            1 1 1 2
                            3 3 3 4
                            ]

Then this property is effectively set to

  '1fr' '1fr'  '1fr'

As there are three implied rows, and each should take up the same amount of space.
