## Как это использовать?
Перед получением `OkHttpClient` необходимо инициализировать настройки игнорирования сертификатов. Для этого вызываем метод:

```java
OkHttpUtil.init(true);
```

После этого можете получить `OkHttpClient`:
```java
OkHttpUtil.getClient();
```

Или вот так:
```java
public class HttpParse {

    static {
        OkHttpUtil.init(true);
    }

    private static final OkHttpClient client = OkHttpUtil.getClient();

    // ... ... ... ... ...

}
```
