<doc>
This block creates a variable with a slider. \
Leave the label blank to use the variable id as the label. \
The value must be a real number. \
The value must be between the minimum and the maximum. \
The number of steps must be between 0 and 1000.
Use the Grid Position (row, column, row span, column span) to position the graphical element in the window.
Use the Notebook Param (notebook-id, page-index) to place the graphical element inside of a notebook page.
