The OpPlaceWeb object defines a website on a ProviewR node.

 The website contains a menu to the left and a start page to the right.

 The menu is divided in three sections. The first contains a number of
 standard functions
 - language selection.
 - login and logout.
 - open alarm and event list.
 - open event log.
 - open runtime navigator.
 - link to project help texts.
 - link to ProviewR documentation.

 These buttons can be enabled or disabled with the Enable/Disable
 attributes in this object.

 The second section contains buttons to open graphs configured with
 WebGraph objects. The WebGraph objects is placed as children to the
 OpPlaceWeb object and contains the name of the Ge graph pwg-file or
 a java class.

 The third section contains links defined with WebLink objects. The
 WebLink objects contains an URL and is positions below the OpPlaceWeb
 object.

 The right page will by default contain the help text for the project,
 written in the file $pwrp_cnf/xtt_help.dat. If another page is prefered,
 this can be stated in the StartURL attribute.

 There can be serveral OpPlaceWeb objects in one node, configuring web
 pages with different settings. The OpPlaceWeb objects should have
 different filenames stated in the FileName attribute, and can be opened
 with an URL to the specified file. The default file is index.html for the
 first OpPlaceWeb object, and index2.html, index3.html etc, for the
 preceeding OpPlaceWeb objects.
