    \class HbSelectionDialog

    \brief HbSelectionDialog class allows user to create a list of options out of which one or more can be selected.  

    SelectionDialog is a modal dialog, for which user has to use default or custom action buttons to dismiss the dialog.

    There are 2 modes of selection for SelectionDialog. SingleSelection or MultiSelection.<br>

    <b>SingleSelection</b>: User can select one item from the list at a time and the SelectionDialog will be dismissed 

    as soon as the user selects the item.<br>

    <b>MultiSelection</b>: User can select multiple items from the list. To dismiss the dialog user has to explicitly press "OK/Cancel" button.

    User can anytime press "Cancel" button to close the dialog without any selection.

    User can provide the data for options in different forms. It can be simple list of strings, list of custom 

    items or a model itself.

    Below is a snippet of code which shows SelectionDialog in a single selection mode.
