further enhanced the emulated sample to allow multiple instances of root
class. this does not mean multiple Postvayler instances with different
roots can co-exist but means for example first element of a  linked list
like structure may be the root. subclasses of root class is also
allowed. looks good for now :)

added some javadoc comments and did some cleanup.
