Description

`open_interval` public member functions

typedef ICL_COMPARE_DOMAIN(Compare, DomainT);

```
open_interval();
```
Default constructor; yields an empty interval (0,0).
```
explicit open_interval(const DomainT & val);
```
Constructor for an open singleton interval (val-1,val+1)

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

Interval from low to up with bounds bounds

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