// ReflectSort will sort slice according to compareFunc using reflection.
// slice can be a slice of any element type including interface{}.
// compareFunc must have two arguments that are assignable from
// the slice element type or pointers to such a type.
// The result of compareFunc must be a bool indicating
// if the first argument is less than the second.
// If the element type of slice is interface{}, then the type
// of the compareFunc arguments can be any type and dynamic
// casting from the interface value or its address will be attempted.
