94  Utility that from an existing Teuchos::ParameterList creates a new list, in
95  which level-specific parameters are replaced with sublists.
96 
97  Currently, level-specific parameters that begin with "smoother:"
98  or "aggregation:" are placed in sublists. Coarse options are also placed
99  in a coarse list.
100 
101  Example:
102  Input:
103  smoother: type (level 0) = symmetric Gauss-Seidel
104  smoother: sweeps (level 0) = 1
105  Output:
106  smoother: list (level 0) ->
107  smoother: type = symmetric Gauss-Seidel
108  smoother: sweeps = 1
