Spell class actor

The Spell class will ultimately do damage to all the monsters. Towards that end, we need to contain both a particle system and a bounding box inside the Spell class actor. When a Spell class is cast by the avatar, the Spell object will be instantiated into the level and start Tick() functioning. On every Tick() of the Spell object, any monster contained inside the spell's bounding volume will be affected by that Spell.

The Spell class should look something like the following code:

UCLASS()
class GOLDENEGG_API ASpell : public AActor
{
  GENERATED_UCLASS_BODY()

  // box defining volume of damage
  UPROPERTY(VisibleDefaultsOnly, BlueprintReadOnly, Category =  Spell)
  TSubobjectPtr<UBoxComponent> ProxBox;

  // the particle visualization of the spell
  UPROPERTY(VisibleDefaultsOnly, BlueprintReadOnly, Category =  Spell)
  TSubobjectPtr<UParticleSystemComponent> Particles;

  // How much damage the spell does per second
  UPROPERTY(EditAnywhere, BlueprintReadWrite...
