  * Reduce tests local redefinitions better.
  
  Previously, collect would gather all the |Int| values
  of a |BinTree Int|. But this could also collect |Int| values
  other than the Tree payload, i.e. weights, balancing info.
  
  So this test now uses a value of type |Tree a b| where the first
  argument is the element type and the second the weight type. The test
  requires that collect only gathers |a| values, excluding any content
  such as the weights even if |a=b| like in |Tree Int Int|
  
  LIGD, GL and GM have been updated. The rest must be done still.
