I have optimized the grid to load much faster and it is reaching a very usable speed.  The problem is I had to remove some good data from the API call in order to get this speed.  For testing, it is working fine.  I will now try to optimize the Grid class further so that I wont have to use such large API calls to retrieve all data and will still be able to display enough relevant information.  This data flaw is only related to the nodes list instantiation of the grid for choosing nodes for association for slices, other uses of the grid should be fine.

Adding sorting is still going to be a problem due to how slow our current sorting function are, relating to the dictionaries returned by API calls.  This is currently the main limitation of the grid and will apply to all future uses of grids anywhere in the GUI.  I will work on making stronger sorting functions in order to optimize this limitation.
