COUNTFORMAT

COUNTFORMAT(range, example_cell, check_background, check_font)
Returns the number of cells that have a particular cell color or font color.

REMARKS
* Returns the number of cells that have been formatted with multiple attributes.
* This function does not recognize formatting if it is applied via conditional formatting.
This function will not update automatically every time a cell format changes although pressing F9 will work.
Need a function that can detect any cell formatting (not a specific colour)
4 Functions that allow you to count different types of formatting.
* You can use the built-in COUNT function to
* You can use the add-in COUNTSUBSTRING function to
