Add expect

[fponticelli]

Should take something like this:

expect(x + y == 3);

And transform into:

var t1 = x,
    t2 = y
    t3 = x + y;
Assert.isTrue(t3 == 3, 'expected `x <$t1> + y <$t2> == 3 <$t3>`');

Not sure if expect should be part of Assert or specific to utest tests.

What about something like:

import haxe.Exception;
import utest.Expect;
import utest.Assert;
import utest.Test;

class FooTest extends Test {
  function testEquals() {
    Expect.value(1).toBeEqualTo(1);
    Assert.equals(1, 1);
  }

  function testRaises() {
    Expect.value(() -> throw new Exception("foo")).toRaise(Exception);
    Assert.raises(() -> throw new Exception("foo"), Exception);
  }

  function testTrue() {
    Expect.value(true).toBeTrue();
    Assert.isTrue(true, true);
  }

  // ...
}
