Fix type being tuple

[stevemk14ebr]

The type list values should also be included. It's an enum from reflect with the values starting at 0, i labeled struct explicitly for example

const (
	Invalid Kind = 0
	Bool
	Int
	Int8
	Int16
	Int32
	Int64
	Uint
	Uint8
	Uint16
	Uint32
	Uint64
	Uintptr
	Float32
	Float64
	Complex64
	Complex128
	Array
	Chan
	Func
	Interface
	Map
	Ptr
	Slice
	String
	Struct = 25
	UnsafePointer
)

I've added an issue for adding an enum (#10). It's been my plan but I have not got to it yet.

Thank you for fixing the mistake and for contributing.
