added very simple reflection example

package reflection

type example struct {

	f1 string

	x1 int

	x2 int

	f2 string

}

package reflection

import (

	"reflect"

	"testing"

)

func TestReflection1(t *testing.T) {

	e := example{}

	eT := reflect.TypeOf(e)

	t.Logf("%s", eT)

	for i := 0; i < eT.NumField(); i++ {

		f := eT.Field(i)

		t.Logf("field: %s - %s", f.Name, f.Type)

	}

}
