feat: multi view plugin

[awesthouse]

This is a new UIPlugin, on the same level as Grid and Table. It could be viewed as an extension of Grid plugin. The purpose of this plug-in is to receive a collection of UI-Recipes and view them with dynamic grid boarders. It also provides the possibility to duplicate a view and put the views side by side, so it could be used to view different part of the data. config may include

• Several different "layout" arrangements: defaults for creating grids.
• options on each item in the start grid as to,
  • possible to close or not
  • possible to create new views from the same or not
  • fixed or possible to resize,
  • size boundaries
• etc

Then the user can create a view like this when inspecting signals, by making a "MultiView" plugin and attach the UI plugin of signal view.
