 \class NmBaseClientPlugin

 \brief The NmBaseClientPlugin plugin provides ui services for IMAP/POP mail protocols.

 The NmBaseClientPlugin contains the following services:
 \li get actions
 \li refresh mailbox
 \li create new email
 \li open settings
 \li send email
 \li delete email
 \li open email
 \li reply email
 \li reply all email
 \li forward email
 \li search emails

 The plugin provides a list of supported UI services as NmAction objects. Actions are connected to
 different public slots and when they are triggered plugin will handle action by itself directly to
 NmUiEngine or by using NmActionResponse to inform user of service.

*/

/*!
    \fn void NmBaseClientPlugin::getActions(const NmActionRequest &request, QList<NmAction*> &actionList)
    Implementation of NmUiExtension interface. The plugin provides to caller supported actions for email protocol.
    \a request contains NmActionRequest with needed request data.
    \a actionList QList array will be filled by action supported protocol and controlled by NmActionRequest.
