The CgiInput class is an abstraction for all input data to the CGI application. This allows input data to come from something other than standard input (cin). This is useful, in fact necessary, when using cgicc with FastCgi. Library users wishing to exploit this functionality should create a subclass and override the read and getenv methods.
