//
// Igor Spaces organises windows (Graphs, Tables, Layouts, Notebooks or Panels) in separate Spaces.
// When a Space is selected in the panel, only windows linked to it are shown. 
// How it works: 
// 1. Launch Igor Spaces from "Windows/Packages" submenu. 
// 2. Press the "New" button to create a new Space, name should be unique, otherwise you will be
// prompted to change your input. When a new "Space" is created it becomes your active working Space.
// New Spaces are created below the active row selection, and at the moment you cannot change their order.
// 3.Press "Delete" to delete the selected space. Windows associated with the space are released and not
// linked to any space ("" tag)
// 4. Press "All" to show/hide all windows whether linked to a Space or not.
// 5. When the Igor Spaces Panel is open any window you create is associated with the active Space.
// 6. Double click on a row to rename the Space
// 7. Press Shift + Click on a row of the ListBox to move the top window to the selected space
// 8. Press Alt + Click anywhere in the ListBox of the panel (rows or empty space below) to pin the top
// window to all spaces (visible everywhere)
// 9. To unpin press Shift + Alt + Click anywhere in the ListBox to unpin the window (becomes free floating).
// You can also make a normal window free-floating using the same procedure. Alternatively, if you want to
// unpin and link it to a space goto 7.
