Checks a label having null set data.

Parameters:

label - the label which is to be checked.

getLabelWithValue

private java.lang.String getLabelWithValue(int val)

Converts label value in integer to String. With addition addes values. For Example. In order 3. If label is 5 or 101 in binary then the String
would be AC. Which represents a set Region AC having members of A and C only,
where possible sets A, B and C.
