## testequal
В этой задаче нужно реализовать 4 test helper'а, аналогичных функциям из [testify](https://github.com/stretchr/testify):
```
func AssertEqual(t T, expected, actual interface{}, msgAndArgs ...interface{}) bool
func AssertNotEqual(t T, expected, actual interface{}, msgAndArgs ...interface{})
func RequireEqual(t T, expected, actual interface{}, msgAndArgs ...interface{})
func RequireNotEqual(t T, expected, actual interface{}, msgAndArgs ...interface{})
```
Пример использования:
```
func TestMath(t *testing.T) {
AssertEqual(t, 1, 2, "1 == 2")
}
```
вывод теста:
```
=== RUN TestMath
--- FAIL: TestMath (0.00s)
math_test.go:43: not equal:
expected: 1
actual : 2
message : 1 == 2
FAIL
FAIL gitlab.com/slon/shad-go/testequal 0.003s
FAIL
```
В отличие от testify реализация ограничивает набор типов, с которыми умеет работать:
1. Целые числа: int, in64 и др (см. тесты)
2. string
3. map[string]string
4. []int
5. []byte
