/** @brief A wrapper class around the Address struct provided by pi-address.h
 *
 * This class allows the user to set and get address field values.
 * For everything but phone fields, the user can simply pass the
 * the pi-address enum for the index for setField() and getField() such
 * as entryLastname.
 *
 * Phone fields are a bit trickier.  The structure allows for 8 possible
 * phone fields with 5 possible slots.  That means there could be three
 * fields that don't have available storage. The setPhoneField() method
 * will attempt to store the extra fields in a custom field if there
 * is an overflow.
 *
 * There are eight possible fields for 5 view slots:
 * - fields: Work, Home, Fax, Other, Pager, Mobile, E-mail, Main
 * - slots: entryPhone1, entryPhone2, entryPhone3, entryPhone4, entryPhone5
 *
 * Internally in the pilot-link library, the AddressAppInfo phone
 * array stores the strings for the eight possible phone values.
 * Their English string values are :
 * - phone[0] = Work
 * - phone[1] = Home
 * - phone[2] = Fax
 * - phone[3] = Other
 * - phone[4] = E-mail
 * - phone[5] = Main
 * - phone[6] = Pager
 * - phone[7] = Mobile
 *
 * Apparently, this order is kept for all languages, just with localized
 * strings.  The implementation of the internal methods will assume
 * this order is kept. In other languages, main can replaced with
 * Corporation.
