## Creation
| CombinationElement (const CombinationElement &e2)
| Copy constructor.

## Operations

| Incrementation.
void | operator-- ()
| Decrementation.
bool | operator< (const CombinationElement &e2)
| Total order comparison.
bool | operator== (const CombinationElement &e2)
| Equality test.
CombinationElement | operator+ (int i)
| Equivalent to calling `++(*this)` `i` times if i is positive.
int | operator- (const CombinationElement &e2)
