Ruby Enumerable methods

A comprehensive rebuild on basic Enumerable methods in Ruby for a better understanding in block passing, enumerator and classes and regular expressions as arguments.

This scripts rebuilds ruby Enumerable methods:

• #each as #my_each
• #each_with_index as #my_each_with_index
• #select as #my_select
• #all? as #my_all?
• #any? as #my_any?
• #none? as #my_none?
• #count as #my_count
• #map as #my_map
• #inject as #my_inject

each of them can be used as default Enumerable methods working the exact same way

Rspec testing for all methods, check (./spec/enumerable_spec.rb) .

Rspec test cases:

1. #my_each with no block passed returns an enumerator
2. #my_each with block passed do a loop routine
3. #my_each_with_index with no block passed returns an enumerator
4. #my_each_with_index with block passed counts index elements
5. #my_select with no block passed returns an enumerator
6. #my_each with block passed returns an Array
7. #my_each with block passed returns an even number array
8. #my_each with block passed fails an .odd? on array
9. #my_all? with no block passed returns true
10. #my_all? with block passed returns true
11. #my_all? with block passed returns true
12. #my_all? with block passed returns false
13. #my_all? with regexp passed returns false
14. #my_all? with class passed returns true
15. #my_any? with no block passed returns true
16. #my_any? with block passed returns true
17. #my_any? with block passed returns false
18. #my_any? with block passed returns false
19. #my_any? with regexp passed returns not true
20. #my_any? with class passed returns true
21. #my_none? with no block passed returns false
22. #my_none? with block passed returns false
23. #my_none? with block passed returns true
24. #my_none? with block passed returns not true
25. #my_none? with regexp passed returns true
26. #my_none? with class passed returns true
27. #my_count with no block passed returns number of elements in an array
28. #my_count with block passed returns number of .even? elements
29. #my_count with block passed returns number of .odd? elements
30. #my_count with block passed returns number of x > 5 elements
31. #my_count with argument passed returns number of element repetition
32. #my_map with no block passed returns an Enumerator
33. #my_map with block passed returns a modified array
34. #my_map with block passed returns a parsed array
35. #my_inject with block passed returns an array sum
36. #my_inject with block passed returns a parsed array
