uploaded the CoFunctionsHelper file, where all supporting functions can be put into a utilities file
added in the helpers array line in order to interface with the CoFunctionsHelper cake file that was created
added in the helpers array line and populated it with the CoFunctionsHelper call so controller knows what this helper is and what it does
the main view or index now also displays the dynamically computed BMI but does not sort by this value given it cannot be known a priori
