## Aurora Interfaces
This library implements the macros required to define Aurora style interfaces. Defines two classes. Implementable by SWIG, CppSharp, and classical OOP override event interface; and implementable by std::function for modern C++ and runtime language bindings respectively. The former is simply defined as a structure containing virtual methods as laid out by AUI_METHODs. Latterly, the base interface is extended and implemented by an array of overloaded method defintions and std::function member fields.


## Example usage:

#### In your common header:
```
#if defined(MY_LIB_GEN_BINDINGS)
    #define LIB_INTERFACE(name, list) AUI_INTERFACE_IMPL(name, list)
#define 
    #define LIB_INTERFACE(name, list) AUI_INTERFACE_FWD(name, list)
#endif 
```

#### In your public API:
```
LIB_INTERFACE(IInputMouseSubscriber, 
    AUI_METHOD(void, onButtonPress, (AuUInt8, mb)),
    AUI_METHOD(void, onButtonTick, (AuUInt8, mb)),
    AUI_METHOD(void, onButtonUp, (AuUInt8, mb))
);
```

#### In a dedicated translation unit:
```
#define MY_LIB_GEN_BINDINGS
#include <...> 
```

#### Usage Runtime Binding and Modern C++
```
// My language binding
IInputMouseSubscriberFunctional test;
test.onButtonPress = [](AuUInt8 btn)
{

};

AuSPtr<IInputMouseSubscriber> handle = AuUnsafeRaiiToShared(&test);
// use handle with an Aurora API 
```

#### Usage C++ Native, SWIG, and CppSharp
```
struct MyEventHandler : public IInputMouseSubscriber
{
    void onButtonPress(AuUInt8 mb) override;
    void onButtonTick(AuUInt8 mb) override;
    void onButtonUp(AuUInt8 mb) override;
}

```

##### Not recommended for small projects and/or people with a shred of sanity left
##### Possibly useful for API developers
