[Cs3] CS3 Lab Header Files

The deal is that .hpp is the now default extension for "pure" C++
header file which may not compile with c-programs. Extension .h
is reserved for files that may be compiled with either c- or c++
programs or just pure c-programs. 

I updated the assignment for lab 2 to ask for file extension
.hpp. Anyone who had it compile with .h extension is free to keep it
the old way.

I am planning to work through the code of CS3 and CSI to replace all
.h extensions to .hpp It will take me some time. Please excuse and any
help is appreciated.

Thanks,
