 * The TeamRoleWildcardAdapter replaces wildcard teamrols like:

 * With the corresponding orgunit name and orgunite uniqueID
 * 
 * {process:Finance:team}
 * 
 * {process:8838786e-6fda-4e0d-a76c-5ac3e0b04071:team}
 * 
 * This notation is supported for the ACL settings in the Modeler.

 * The Adapter is called by the method 'mergeValueList' from the AbstractPlugin.
