Dictionary client class package: Client dictionary class

A base class and 2 derivated classes to generate clients for dictionary servers
that follow the DICT protocol (RFC 2229), such as the server at dict.org

Included also 2 examples of query interfaces generated using these classes, one performs
a simple search, and the other shows how to get information from the dictionary server
and use that to generate a form allowing for more complex searches.

[UPDATE: 2000/06/05] Fixed some bugs reported by Davor Cengija <davor@croart.com> and
found another bug related to URLs referred in the definition that are also marked as
crossrefence terms

[UPDATE 2000/06/06] Check for duplicates when creating the links, and
modified the external URLs regex to recognize more protocols, as well
as eliminate crossreferences to RFC's (example scripts)

[UPDATE 2000/06/07] Stoyan Jekov noticed that I forgot to close my HTML FORM element
