Represents an ability to convert bean of type B to generic representation (shapeless.HList). This is almost the same with shapeless.Generic, but for JavaBeans. E.g:

public class Cat {
    private String name;
    private int age;

    public String getName() { return name };
    public void setName(String name) { this.name = name; }

    public int getAge() { return age; }
    public void setAge(int age) { this.age = age; }
}

Then the BeanGeneric instance will have Repr = String :: Int :: HNil. Note that the HList order is the same with the bean properties getters declaration order.

Now it's possible to convert bean to HList, and then convert HList to something else.
