The Navigation sheet is the JZR report home page and the entry point for all the other Jeyzer sheets.
It lists the Jeyzer sheets in their declaration order and provides the access link to each of them.
It also displays the sheet description as defined in the related Jeyzer sheet configuration (or the one by default if not present) and the number of items and graphical resources/charts (in parenthesis).
Sheet entry gets highlighted if the related sheet contains critical events : highlight color is the one defined in the target Jeyzer sheet configuration.
At last a smart quote is randomly generated on the top right of the sheet.
