    Description copied from class: StatementBlock
    
    Updates the repetition estimate for this statement block and all contained hops. FunctionStatementBlocks are loaded from the function dictionary and repetitions are estimated for the contained statement blocks. This method is overridden in the subclasses of StatementBlock.
    
    Overrides:
    
    updateRepetitionEstimates in class StatementBlock
    
    Parameters:
    
    repetitions - estimated for this statement block
