Add summarize(data, model::JuMP.Model)

Would it be possible to translate the MOI stuff back to JuMP?

* Variable: MOI.VariableIndex(31914)
* Variable: MOI.VariableIndex(31915)
* Variable: MOI.VariableIndex(31916)
```

is not as helpfull as

```md
## List of issues

Showing first 10 issues (37 issues ommitted)

* Variable: $(JuMP.all_variables(model)[31914])
* Variable: $(JuMP.all_variables(model)[31915])
* Variable: $(JuMP.all_variables(model)[31916])
```

Same for the constraints:

```julia
MathOptInterface.ConstraintIndex{MathOptInterface.ScalarAffineFunction{Float64}, MathOptInterface.GreaterThan{Float64}}(518)
```
```julia
JuMP.all_constraints(model, JuMP.AffExpr, MOI.GreaterThan{Float64})[518]
```

Start at the requested summarize(data, model::JuMP.Model) entry point and review how the current output renders MOI.VariableIndex and constraint indices. Use the examples in this issue as the target behavior; done means variables and constraints are reported through their corresponding JuMP representations.
