#14 VCS contains cruft with no obvious use

[Wesley J. Landaker]

There are quite a few places where the VCS contains cruft with no obvious use. For example, the files in misc/xilinx may have something to do with the csv2phdl parser, but serve no purpose in their present location. For another example, in phdl-2.1/tutorials/src/guice there are files that appear to be a demonstration of how to use a certain library, but obviously PaymentVisaCard.java is not an important part of PHDL (maybe once we start taking donations!). There are many other examples, but basically we just need a general janitorial sweep.

I've cleaned out the named examples, plus a few other obviously harmless things.

There still needs to be a more major invasive janitorial effort, but it needs to be done a little more carefully so as not to break anything. =)
