// PID.js
// 2007.09.12 - written by rk7138 for AT&T Communications
// 2007.10.08 - added ancestor, children, parent, sibling methods
// 2007.10.12 - added environs [] from the domain extracted for URI
// 2007.10.17 - added remainder of PIDs to have them redirect to a valid 
//				LeftNavigation PID
//-----------------------------------------------------------------------------
// ASSUMES
// - writeHTML.js is loaded [ uses getQueryParameter(); }
// - PID.infoArray[] is in the order of desired presentation
//
// METHODS
//   getInfo (givenId, bIsPID) returns Hash or undefined
//   getLastSiblingId (givenId, bIsPID) returns Array index or -1
//   getNextSiblingId (givenId, bIsPID) returns Array index or -1
//   getParentId (givenId, bIsPID) returns Array index or -1
//
//   getChildrenIds (givenId, bIsPID) returns Array or -1
//	 getSiblingIds (givenId, bIsPID) returns Array or -1; will return self node
//   getAllParentIds (givenId, bIsPID) returns Array or -1
//
//   - givenId needs to be the array index for PID.infoArray[]
//   - if bIsPID is true, then givenId can be the Teamsite PID key such as 10481
//   - the PID key may contain a hash anchor such as 10505#basic
//
// USAGE  
//   pidObj = PID.getInfo(10473, true); //RETURNs level, label, token, target, tooltip via PID
//   pidObj = PID.getInfo(10473, false); //RETURNs level, label, token, target, tooltip; via Node ID
//
// INFORMATION
//   used by Breadcrumbs.js generate breadcrumb tokens based on current PID viewed
//   used by LeftNavigation.js to generate navigation tree and to select link of current PID viewed
//
//   the PID.init() must be called from LeftNavigation.js or Breadcrumbs.js
//
//	 if the token is '', then use the value of the label when calling PID.getInfo(..., false)
//   
//   if the target is '', then link is for existing pid
//   if the target is #something, then link is for existing pid#something
//   if the target is {test:'a', prod:'b', tooltip: ''}}, then link is a redirect to test or prod contextually
//
//   set duplicate = true for the second or third occurrence of any entry to force menu to remember it's
//   last nodeId when it redraws; effectively showin the first instance for page content by still
//   focussing on the last nodeId for drawing the navigation tree
