A Set implementation that supports **Objects** and **custom conditions**.

## Usage

```js
const ObjectSet = require('object-set-type');

const set = new ObjectSet();
set.add(1);
set.add('Hello');
set.add({
    a: 1
});
set.add({
    a: 1
});

console.log(set.size); // 3
Array.from(set); // 1, "Hello", {a: 1}
```

## Custom comparison logic

The `equals(a,b)` method is responsible for comparing two items, and the set logic is based on this. This method can be overwritten to support custom uniqueness logic, e.g., handle objects, but compare only specific properties.
