/**
* CFindItemDialog dialog class
*   This is an interface class for applications to use FindItem.
*   Derived from CAknDialog to enable options menu.
*
* Usage:
*   ----------------------- Copy & Paste -------------------------------
*   CFindItemDialog* dialog = CFindItemDialog::NewL( text, searchCase );
*   dialog->ExecuteLD();
*   --------------------------------------------------------------------
*
*   Text has to be given to dialog as a descriptor.
*   If the application's text is an object derived from CEditableText,
*   like in CEik* editors, there's two possible things that can/need to be
*   done depending on the type of in-memory buffer used:
*       If the text is as a flat buffer, a descriptor can be fetched using
*           TPtrC text = iRichText->Read(0);
*       otherwise a new descriptor need to be created and e.g. richtext's
*       Read() method needs to be called as long as the whole text is
*       inserted to descriptor.
*
*   The dialog will be automatically destroyed by ExecuteLD.
*
*   Use CFindItemMenu class to insert finditem-menuitems to your
*       application's menu. See: finditemmenu.h for more info
*
*   Note ! NewL stores a reference to the text passed as a parameter and
*           uses it when the dialog gets executed so it should not be deleted
*           before the dialog is dismissed.
