    \class HbSelectionDialog

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

    HbSelectionDialog is a modal dialog which means once it is displayed, user can not perform any action

    untill dialog is closed.

    There can be 2 modes of selection. SingleSelection or MultiSelection. If it is SingleSelection, dialog is closed

    as soon as user clicks one of the options.In case of MultiSelection, user has to explicitly press "OK" button to

    close it after selecting the item(s). User can anytime press "Cancel" button to close the dialog without selecting 

    anything.

    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.
