Class: AlternarColor array iterator

This is a very simple class that iterates over a set (of color codes or names maybe?) and returns the next element in the set on each iteration, coming to first element again.

It can be useful for generating listings with rows using alternated colors.

The class can take an array with an arbitrary number of colors names or values.

In the first iteration it returns the first color in the array. In the next iteration it returns the following color, and so on. When the end or the array is reached, it returns the first color again.

The comments in the class are in Spanish.
