Adding makefile

Since the project is required to be worked under the Apache© Ant the
build.xml is fulfilled today. It creates the ./bin folder as the build
folder. Then all compiled classes are redirected to that folder.
The target "run" still doesn't work so far.
The interface class(the impl package) should be compiled into jar in the
future.

The runnable ant script

The run target in the build.xml is fixed. Simply type "ant run" can
bring up the program without any annoying parameter passing to java.
Still bear in mind that you need to kill the server and rmiregistry
daemon manually.
