/**
* CLmkEncodeUnsavedLandmarksOp class.
* This class does landmarks encoding operations.
* Though there is already one operation's class which does this in the

* landmarks which existis in landmarks database, but this class is does not
* requires any landmarks database assistance, it independently encodes the
* landmarks to xml format.
