+--[[
+		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
