An example of use of inheritance in object passing.

* description

This example is a revised version of examples/interfaceSend. Thus
it essentially does the same thing as examples/interfaceSend.

Class Data is a two dimensional array. Client sends an object of
Data to Server and Server send back it to the Client.

Class Triangle is a two dimensional triangular array and is implemented
as a subclass of class Data. Thus it has only constructor methods
for building a triangle array. Server treats Traiangle as if it is
Data.
