 /**
 34  
  * The MuleContextInitialisePhase defines the lifecycle behaviour when the Mule context is initialised.  The MuleContext is associated
 35  
  * with one or more registries that inherit the lifecycle of the MuleContext.
 36  
  * <p/>
 37  
  * This phase is responsible for initialising objects. Any object that implements {@link org.mule.api.lifecycle.Initialisable} will
 38  
  * have its {@link org.mule.api.lifecycle.Initialisable#initialise()} method called.  Objects are initialised in the order based on type:
 39  
  * {@link org.mule.api.transport.Connector}, {@link org.mule.api.agent.Agent}, {@link org.mule.api.model.Model}, {@link org.mule.api.service.Service}, followed
 40  
  * by any other object that implements {@link org.mule.api.lifecycle.Initialisable}.
