Team refactor

Refactoring of a sample Ruby class.

This is just a simple experiment. The most interesting bit is the usage of Ruby 2.2.0's itself method (at Team#print_member_names).

Improvements

The refactor I did in the Team class was driven by the following objectives:

1. To make method names unambiguous: #<< became #add_member and #presentation_print became #print_member_names

2. To make the implementation simpler and shorter: see #add_member and #print_member_names

3. To use attribute accessors (the advantage over instance variables is to be able to transform the data when setting or getting)

4. To replace all print methods with just one. The new #print_member_names solves the problem with a functional programming inspired approach. Besides that, it is also simple and very flexible

Usage

First, clone this repo.

Then, install the gems by running bundle install.

The only gem actually used is RSpec.

To run the specs, execute bundle exec rspec.
