Display multi-dimensional arrays under collapsible trees as 1D arrays

[Francesco Casella]

Simulate the following model in OMEdit

model Arrays
  Real x[10]      = fill(1,10);
  Real y[10,10]   = fill(1,10,10);
  Real z[10,10,3] = fill(1,10,10,3);
end Arrays;

The array {x} appears in the Variables Browser under a collapsible tree. Unfortunately y and z don't, they flood the browser with all the expanded scalar elements. We shoud probably have hierarchical collapsible trees of elements for the ND arrays as well.
