CgiParser is a Cgi parser library written in C++, which can be used as a stream class,
thanks to operator overloading. CgiParser supports both GET and POST methods, and does so automatically
just as it does for everything else.
All one has to do to write cgi programs using this library is the
include this header, and create an object of this class. The object can
be used with the << operator to print variables from HTML forms.
