    Parameters:
    
    cs - the CharSequence to be processed.
    
    ignoreCase - whether or not to be case-insensitive.
    
    thisStart - the index to start on the cs CharSequence.
    
    substring - the CharSequence to be looked for.
    
    start - the index to start on the substring CharSequence.
    
    length - character length of the region.
    
    Returns:
    
    whether the region matched.
