Constraints (biojava 4.2.1 API)

java.lang.Object
- org.biojava.nbio.aaproperties.Constraints

```
public class Constraints
extends Object
```
This class is used to support the implementation of properties stated in IPeptideProperties. It initializes several values that would be needed for the computation of properties such as
Molecular weight
Instability index
Hydropathy value
pKa
