fa87eca375 Add new class Set for simple Set-theoretical operations 
### Features

* Works only with primitive types int, float, string
* Implements set theortic operations union, intersection, complement
* Modifies set by adding, removing elements
* Implements \IteratorAggregate for use in loops

### Implementation details

Based on array functions:
* array_diff,
* array_merge,
* array_intersection,
* array_unique,
* array_values,
* sort.

### Drawbacks

* **Do not work with objects.**
* Power set and Cartesian product returning array of Set
