/**
* Helper class to capture a user's restrictions (access rights, profiles...) as a set of limiting conditions
*
* **** NOW OBSOLETE *** SHOULD BE REPLACED EVERYWHERE BY UserRights *****
*
*
*
*
* Usage:
* 1) Build the user's context (from her rights, a lookup in the database, a cookie, whatever)
* $oContext = new UserContext();
* $oContext->AddCondition('SomeClass', 'someFilter', 'SomeValue', '=');
* ...
*
* 2) Use the restrictions contained in the context when retrieving objects either when:
* getting directly an instance of an object
* $oObj = $oContext->GetObject('myClass', 'someKey'); // Instead of $oObj = MetaModel::GetObject('Klass', 'someKey');
* or when building a new search filter
* $oFilter = $oContext->NewFilter('myClass'); // Instead of $oFilter = new CMDBSearchFilter('Klass');
