Pull request description:
Before this commit:
```c++
for (std::map<T1, T2>::iterator x = y.begin(); x != y.end(); ++x) {
T1 z = (*x).first;
…
}
```
After this commit:
```c++
for (auto& x : y) {
T1 z = x.first;
…
}
```

* Variable-length integers: bytes are a MSB base-128 encoding of the number.

|
* The high bit in each byte signifies whether another digit follows. To make
|

* sure the encoding is one-to-one, one is subtracted from all but the last digit.
|
|
* Thus, the byte sequence a[] with length len, where all but the last byte
|
|
* has bit 128 set, encodes the number:
|
|
*
|

* (a[len-1] & 0x7F) + sum(i=1..len-1, 128^i*((a[len-i-1] & 0x7F)+1))

* Properties:
|
|
* * Very small (0-127: 1 byte, 128-16511: 2 bytes, 16512-2113663: 3 bytes)
|
|
* * Every integer has exactly one encoding
|
|
* * Encoding does not depend on size of original integer type
|
|
* * No redundancy: every (infinite) byte sequence corresponds to a list
|
|
* of encoded integers.
