--[[
		A simple component that allows you to bind to ContextActionService at CoreScript level

		Props
			name - the name of the binded action
			callback - the function that is invoked
			binds - the input that triggers the action
				this is a table - example { Enum.KeyCode.ButtonA, Enum.KeyCode.ButtonX }
			actionPriority - the action priority
		Usage:
			ContextActionCn = Roact.createElement(ContextActionEvent, {
				name = "MyContextActionBind",
				callback = function() print("context event") end,
				binds = { Enum.KeyCode.Thumbstick2, Enum.KeyCode.ButtonB, Enum.KeyCode.A },
				actionPriority = 1,
			}),

		Note: Cannot currently write a unit test for this component because it uses functions that
		are RobloxScript security. LuaCore team is looking into a solution for this
