* Description: 
*
*     Store and handle text labels for note dialogs. Each note dialog
*     can have two different labels, one singular and one plural.
*     For example:-
*        "You have 1 new message" is the singular label and
*        "You have 2 new messages" is the plural label.
*     This class supports the ability to change number inside the label, 
*     e.g. "You have 100 new messages" is supported.
*     Text is read from resource but can also be set dynamically via the
*     public API.

/**
 * An avkon dynamic text class. 
 *
 * Manage static or dynamic text. Static text never changes,
 * e.g. "Delete?". Dynamic text changes depending on a number,
 * e.g. "Delete 1 message?" or "Delete 3 messages?"
 *
 * Client can specify plurality and/or number to determine which
 * text is returned. 
 *
 * Formatted text is stored in a buffer, there are then 2 additional
 * buffers storing the unformatted texts, e.g. "Delete %d message"
 * and "Delete %d messages".
 *
 * One current limitation is that only one number can be supported 
 * per text. A better approach would be to offer a printf alike interface.
 * In fact the whole idea of the control having to manage these texts
 * is a bit of a nonsese - the client should simply call a method
 * passing a text a number of args, like when calling printf. For future
 * implementations.
