Creates a Hook with the given:
priority: some comparable object. only used if you place the
hook in a HookList.
function: can be any callable
if the given argument for function is not a callable,
it will be wrapped to a function which always returns
that argument (a constant of sorts)
args: arguments that will be passed to function
when this hook is called
Examples:
h1 = Hook(0.0, lambda a, b: a + b, (1, 4))
h1() # 5
h2 = Hook(0.0, 27, ())
h2() # 27
h3 = Hook(7.2, lambda a, b, c: a + b + c, (1, 4))
h3(8) # 13
