code: public <T> T all(String entityName, String groupId, Class<T> clazz) throws MnoException {
  		return all(entityName, groupId, null, getAuthenticatedClient(), clazz);
  	}
docs: Return the entities in a typed class. The typed class should contain a field "entityName" with the list of entity class. For example:
  
  <pre>
  {@code
  class Organizations{
  private List<Organization> organizations;
  public List<Organization> getOrganizations(){
  return organizations;
  }
  }
  class Organization{
  public String getId();
  //etc...
  }
  </pre>
  
  @param entityName
  @param groupId
  @param clazz
  @return
  @throws MnoException
