Robert Maynard 89fa2c0293 Remove multiple vtkm::cont::CellSet from vtkm::cont::DataSet
By removing the ability to have multiple CellSets in a DataSet
we can simplify the following things:

  - Cell Fields now don't require a CellSet name when being constructed
  - Filters don't need to manage what the active cellset is
