/****

*
*
* DocHost2 - second attempt at the WAB Doc Host interface
*
*
*    Purpose:
*        basic implementation of a docobject host. Used by the body class to
*        host Trident and/or MSHTML - when we do LDAP searches, LDAP providers
-       are allowed to return URLs in the LDAPURI attribute. WAB then addds
-       a "general" property tab that hosts trident and shows the contents
-       of the URL within the WAB. This allows the providers to add ADs and
-       branding to their data to diffrentiate themselves from each other.
-       Oh, the things we do for business relationships ... 
*
*  History
*      August '96: brettm - created
*      Ported to WAB - vikramm 4/97
