Hint markup element and table column hint

[timka-s]

Goal: Fast help for user to use charts

1. New function - Hint(content: Markup, body: Optional[Markup])
   When user hover hint body - he view hint box
   

If body not defined - use some default hint symbol, like ℹ️

2. New property group for Table column - hint
   If enabled - after column name added hint

An additional example of usage in a calculated field:
SquareTextField = Markup(SquareField, Hint(Markup("Formula is ", Bold("Pi * R * R"), ", where ", Bold("R"), " is", RadiusField), Bold("?"))

@timka-s hi! We are glad to inform you that we've implemented hint for selectors and table headers.
It is available on recent version of containers images.
