87396ebe58 DecisionTree and Fuzzy C Means classifiers (#35)
* Fuzzy C-Means implementation

* Update FuzzyCMeans

* Rename FuzzyCMeans to FuzzyCMeans.php

* Update NaiveBayes.php

* Small fix applied to improve training performance

array_unique is replaced with array_count_values+array_keys which is way
faster

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

c8bd8db601 # Association rule learning - Apriori algorithm
* Generating frequent k-length item sets
* Generating rules based on frequent item sets
* Algorithm has exponential complexity, be aware of it
* Apriori algorithm is split into apriori and candidates method
* Second step rule generation is implemented by rules method
* Internal methods are invoked for fine grain unit tests
* Wikipedia's train samples and an alternative are provided for test cases
* Small documentation for public interface is also shipped
