        // to convert a kebab-case $field to a function name, we want to 
        // convert it to StudlyCaps.  so, first, we convert from kebab-case to 
        // camelCase and then we ucfirst() the camelCase string to make it 
        // studly.  finally, we add the word "validate."  Thus, a start-date
        // field becomes startDate, then StartDate, and finally we return 
        // transformStartDate.

        // we're less concerned with format (a transform can standardize 
        // that).  here, we just want to know that what we have might be
        // a date which is a good job for strtotime()!
