Given a number, format it properly for textual display using the notation $xxx,xxx,xxx.xx. Assume that no more than two digits will follow the decimal point (i.e. you don't have to worry about rounding). Indicate negative numbers with parentheses.

Examples:

Input amt = 34.2 Output str is '$34.20'

Input amt = 91337585 Output str is '$91,337,585.00'

Input amt = -63234922.46 Output str is '($63,234,922.46)'

Input amt = 2784.9 Output str is '$2,784.90'

interesting use of strread to turn a string into a cell array (though probably only really useful in cody)
