Tactic Documentation:

## Tactic add-bounds

### Short Description

Tactic for bounding unbounded variables.

### Long Description

The tactic creates a stronger sub-goal by adding bounds to variables.
The new goal may not be satisfiable even if the original goal is.

### Example

```z3
(declare-const x Int)
(declare-const y Int)
(assert (> (+ x y) 10))
(apply add-bounds)
```
