class_docstr: Control the creation and navigation of an hSNE manifold model
  using appropriate visualization and interaction GUIs depending on the data.
  This controller assumes that selections are hierarchical and that each
  selection produces a new GUI for viewing and further selection.

  Callback remove an analysis in the analysis model
