DESCRIPTION
     This is a modification from CGI_LIB.pl.

     CGI_LIB.pm module does not have complicated/powerful functions that
     CGI.pm have. It just a simple module which helps you to process the
     CGI input, i.e. the submitted form data. Of course, it supports
     HTTP File Upload.

     For a NT user, bimode(FILEHANDLE) is needed after the FILEHANDLE is
     created when we try to save a binary uploaded file, like .gif and .jpg
     files.

     When you create the CGI_LIB object by using "new CGI_LIB()", the
     module will automatically process the data according to the form
     method used ( "GET" or "POST" ) and the "Content-Type" of the
     submitted data ( "application/x-www-form-urlencoded" or
     "multipart/form-data" ). And the module will set the data into the
     object.

     Getting Data From The CGI_LIB Object:
     $obj->{'field_name'}, where "field_name" is the name that you set
     insides the "input" HTML tag.

     There are three types of variables that you will get from the
     CGI_LIB object.

     Single Value :
       Contains only one value.
       eg. <input type="text" name="emailaddress" size="40">
       If the user key in "userid@domain.com" into this text box,
       $obj->{'emailaddress'} will give you "userid@domain.com".

     Array Reference :
       Contains multiple values, like multiple "select"ion and "checkbox".
       eg. <input type="checkbox" name="hobby" value="0">Computer
           <input type="checkbox" name="hobby" value="1">Reading
           <input type="checkbox" name="hobby" value="2">Travelling
       If the user checks all the three checkboxes, $obj->{'hobby'} will
       contains the reference of an array.
       @{$obj->{'hobby'}} will contains "0", "1" and "2".
       ref($obj->{'hobby'}) will return "ARRAY".

     Hash Array Reference :
       Basically, this variable will contain the uploaded file's
       information. It consists of the following fields:
       name : The name used in the "input" HTML tag.
       filename : The uploaded file's name.
       content-type : The "Content-Type" of the uploaded file.
       contents : The content of the uploaded file.
       size : The size of the uploaded file.
       eg. <input type="file" name="afile">
       If the user select a file, C:/test.txt, and contains
       "This is a test file.".
       $obj->{'afile'}->{'name'} = "afile"
       $obj->{'afile'}->{'filename'} = "C:/TEST.TXT"
       $obj->{'afile'}->{'content-type'} = "text/plain"
       $obj->{'afile'}->{'contents'} = "This is a test file."
       $obj->{'afile'}->{'size'} = 20
       ref($obj->{'afile'}) will return "HASH".
       
     Errors, comments or questions are welcome.
