Client Side message support in JLDAP's DSML Library

["Sunil Kumar" <Sunilk@novell.com>]

Hi,      
    I have completed an implementation in JLdap where you will be able
to Write Any of the LDAP messages using DSMLWriter class.
Earlier it use to  have just server side message support and it
understands only LDAPSearch Results and Add Response, Modify Response,
ModifyDN Response, Delete Response, Compare Response and extended
operation Response.

After this Implementation DSMLWriter  will also be able to write
LDAPSearch Request, LDAPAddRequest, LDAPModifyRequest, 
LDAPModifyDNRequest, LDAPDeleteRequest and LDAPExtended Operation. I
guess this is what requested by Marc a few days ago in this List. Let me
know if your comments about it.  I have checked in the changes in the
Openldap CVS Repository.

Also find a Sample code below to Test this functionality:-
