Description

`closed_interval` public member functions

typedef ICL_COMPARE_DOMAIN(Compare, DomainT);

```
closed_interval();
```
Default constructor; yields an empty interval [0,0).
```
explicit closed_interval(const DomainT & val);
```
Constructor for a closed singleton interval [val,val]

closed_interval(const DomainT & low, const DomainT & up);

Interval from low to up with bounds bounds

```
DomainT lower() const;
```
```
DomainT upper() const;
```
```
DomainT first() const;
```
```
DomainT last() const;
```
