    // sorts an input array $inLabels() for presort bundles

    // Inputs:
    // $inLabels() is a 2-d associative array which must have:
    //  "Zip" as the location of the zipcode,
    //  the array is generally of the form
    //      $Labels[$i] = array('Name'=>$name, 'Address'=>$address,...'Zip'=>$zip)

    //  Bundles will be returned in the following order:
    //  Bundles where full 5 digit zip count >= $iZip5MinBundleSize
    //  Bundles where 3 digit zip count >= $iZip3MinBundleSize
    //  Bundles where "ADC" count >= $iAdcMinBundleSize
    //      Mixed ADC bundle
    //
    // Return Values:
    // (1) The function returns an associative array which matches the input array containing any
    // legal bundles of "type" sorted by zip
    // (2) if no legal bundles are found for the requested "type" then the function returns "FALSE"
    // (3) the output array will also contain an associative value of "Notes" which will contain a
    //     text string to be printed on the labels indicating the bundle the label is a member of
    //
    // Notes:
    // (1) The ADC data is hard coded in the variable $adc was composed march 2006
    // (2) the definition of a "legal" bundle is one that contains at least $iMinBundleSize units
    // (3) this function is not PAVE certified
