## Installation

The recommended way to use this library is via [Composer](http://getcomposer.org/).

### Composer

To add this package as a local, per-project dependency to your project, simply add a
dependency on `data-values/common` to your project's `composer.json` file.
Here is a minimal example of a `composer.json` file that just defines a dependency on
version 0.3 of this package:

    {
        "require": {
            "data-values/common": "0.3.*"
        }
    }

### Manual

Get the code of this package, either via git, or some other means. Also get all dependencies.
You can find a list of the dependencies in the "require" section of the composer.json file.
Then take care of autoloading the classes defined in the src directory.

## Tests

This library comes with a set up PHPUnit tests that cover all non-trivial code. You can run these
tests using the PHPUnit configuration file found in the root directory. The tests can also be run
via TravisCI, as a TravisCI configuration file is also provided in the root directory.
