// index is invalid, null is returned. If data exist, but is not of the type 
// integer, null will be returned. Yes, it is not a typo. Bools are transmitted
// as integers, however this function does check that the received integer is
// 0 or 1, otherwise null is returned as well.
// @param index position in the Data array to grab
// @return Data[index] if it exist and is of the type integer and is 0 or 1, otherwise null
