Using Physics Lab software

Options available to do with make:
	- $make : compile the software and generates PhysicsLab.jar
	- $make run : excecute PhysicsLab.jar (of course, just if its exist).
	- $make doc : process all the classes documentation. Its saved at ./documentation
	- $make clean : remove all the .class and .jar files.
	- $make cleandoc : remove the documentation directory (recursively).

That's all folks. We wish you to enjoy the software.
