    Utility that from an existing Teuchos::ParameterList creates a new list, in
    which level-specific parameters are replaced with sublists.

    Currently, level-specific parameters that begin with "smoother:"
    or "aggregation:" are placed in sublists. Coarse options are also placed
    in a coarse list.

    Example:
    Input:
    smoother: type (level 0) = symmetric Gauss-Seidel
    smoother: sweeps (level 0) = 1
    Output:
    smoother: list (level 0) ->
    smoother: type = symmetric Gauss-Seidel
    smoother: sweeps = 1
