Changes for plate map image intensity merge
Added wellwise plotting combination, work in progress on datatip browser.
Tested functionality for interactive plot browser.

    %TODO - expand for arbitrary metadata parameters
    %TODO - turn on and off using contextmenu - also perhaps change tip style (window/datatip)? Ability to turn off draggable, too?
    %TODO - call as function from external .m file?
Fixed(/work around) error with x variable sometimes being a cell array.
Commentd out try-catch to let errors be handled elsewhere?
Removed extraneous lines
