code: public Column doCreate(Column column) {
      String url = getDefaultUrl();
      return restClient.doPost(url, column, GsonTypeTokens.COLUMN);
    }
docs: Actually perform the create call to Kanbanery, and don't use a flow to build the call.
  You will most probably want to use the {@link #create(Column)} method most of the time.
  
  @param column the column data to be used for the new column
  @return the freshly created (and populated) column
  @throws ServerCommunicationException if the server response could not be fetched
