Add more source programs from other concurrent compilers if possible, and add sequential programs as well

[GregoireDerrough]

Currently the existing example programs should be good enough to demonstrate the capabilities of Pascal-FC I should think, but adding some more example programs might not hurt. I already have several documents from the original authors that include example programs that are not included in their releases of Pascal-FC, as well as from other authors.
Could also add some sequential programs to demonstrate it's sequential capabilities. I have the "A collection of pascal programs" from professor Wirth, those could be good to add.
