## Methods
```gdscript
hook.GetTable()
hook.Add(event: String, uid: String, function: FuncRef)
hook.Call(event: String, args: Array)
hook.Remove(event: String, uid: String)
```

## Usage
`hook.Add` creates a new listening event and `hook.Call` executes all listening events of the same type, for example:

```gdscript
# autorun.gd

func printHookOutput1(a: String, b: String):
    print(a, " ", b)
    
func printHookOutput2(a: String, b: String):
    print(a, " ", b)

hook.Add("OnReady", "UniqueName1", funcref(self, "printHookOutput1"))
hook.Add("OnReady", "UniqueName2", funcref(self, "printHookOutput2"))
```
```gdscript
# any node script

func _ready():
    hook.Call("OnReady", ["Hey!", "It's OnReady hook!"])
```

`hook.Remove` removes any listening event by its name and type:

```gdscript
# can be executed in any place

hook.Remove("OnReady", "UniqueName")
```

`hook.GetTable` returns a `Dictionary` with all added listening events

```gdscript
# can be executed in any place

var hookTable: Dictionary = hook.GetTable()
```
