### SerializableCallback

Lets you drag-and-drop methods with or without return values / parameters in the Unity inspector.

It uses expression trees and reflection to cache a delegate on first execution.

Usage is identical to UnityEvent

```csharp

public class MyClass : MonoBehaviour {

    //These fields are shown in the inspector

    public SerializableCallback callback; // supports all non-void return types

    public Condition condition; // supports bool return types only

    public GetProduct getProduct; // supports MyProduct return types only

    void Start() {

        // Callbacks can be invoked with or without parameters, and with different types

        Debug.Log(callback.Invoke()); // returns object

        Debug.Log(condition.Invoke()); // returns bool

        Debug.Log(getProduct.Invoke(2)); // returns MyProduct

    }

    // As with UnityEvents, custom callbacks must have a non-generic wrapper class marked as [Serializable] in order to be serialized by Unity

    [Serializable]

    public class Condition : SerializableCallback {}

    // Last generic type parameter is the return type, staying consistent with System.Func

    [Serializable]

    public class GetProduct : SerializableCallback {}

}
