Instead of:

let { x : A;
      x := y } in z;

We want to type:

let x : A := y in z;

With the shorter syntax we should allow omitting the braces. Otherwise it gets unnecessarily verbose, in my opinion.

Restructure the documentation and add a tutorial (#1718)
b95abea 
* Closes #1597 
* Closes #1624 
* Closes #1633 

The tutorial uses syntax which has not been implemented yet: it depends
on
- #1637, 
- #1716, 
- #1639,
- #1638.

The tutorial also assumes the following issues are done: 
- #1720, and
- #1701.

@lukaszcz I agree. Moreover, since the braces for let expressions serve no purpose, I think we should get rid of them entirely. See #1786

Allow type signatures to have a body (#1785)
38622b2 
- Closes #1637.

A function type signature is now allowed to have a body. This is valid
for both top level and let definitions.
```
not : Bool -> Bool := λ {
 | true := false
 | false := true
};
```
