## Purpose

Small Ruby module for sorting an array of integers by frequency.

## Usage:

    ruby sort_by_frequency.rb [  ... ]

## Caveats

* The CLI coerces arguments into Fixnum, but

  SortByFrequency#sort_integers currently does not.

* The behavior of the method when comparing alphanumerics, strings,

  mixed-type data, or anything else is currently undefined.

## Compatibility

The module was tested against Ruby 1.9.3-p125 on the MRI interpreter.

## Examples

    # Use default data set.

    ruby sort_by_frequency.rb

    # Use custom data set.

    ruby sort_by_frequency.rb 1 2 2 2 3 3

## Sample Output

This is an example what you should see when running sort_by_frequency.rb

from the command line.

    $ ruby sort_by_frequency.rb

    [1, 2, 2, 2, 3, 3]

    [2, 3, 1]

The first line of output is the raw data set, and the second is the

sorted list of integers by frequency.
