UPROPERTY type

The uprops macro

The uprops macro is used to mark fields in Nim as UPROPERTY in Unreal Engine. It can be used only from within the uClass macro. ???

uprops allows for specifying multiple fields at once - all of them will be marked as UPROPERTY with the provided specifiers.

## Example

```nim
uClass AMyActor of AActor:
  (BlueprintType, Blueprintable)

  uprops(EditAnywhere, BlueprintReadWrite):
    exampleValue : FString
    intVale : int32
    someDoubleValue : float64
    predValue : FString = "Hello"
    startPos: FVector = randomPos()
