Develop PHPUnit tests capable of being run in situ

[bobbingwide]

Using the functionality of oik-batch and wordpress-develop-tests, develop PHPUnit tests for the bbboing plugin that are capable of being run in situ.

Three files are required in the repo

1. phpunit.xml.dist - contents as below (initially)
2. phpunit.json - the most recently run test output
3. tests/test-bbboing.php - the source for the tests

<phpunit
    bootstrap="../oik-batch/oik-wp.php"
    backupGlobals="false"
    colors="false"
    convertErrorsToExceptions="true"
    convertNoticesToExceptions="true"
    convertWarningsToExceptions="true"
    >
    <testsuites>
        <testsuite>
            <directory prefix="test-" suffix=".php">tests/</directory>
        </testsuite>
    </testsuites>
</phpunit>

The tests will be dependent upon https://github.com/bobbingwide/oik-batch and
https://github.com/bobbingwide/wordpress-develop-tests

I'm developing with PHP 7 and had some problems with PHPUnit v4.8.0
These have been fixed in PHPUnit v5.5.0 so I'm using that now.
So far I haven't had any insurmountable problems with v5.5.0
Time will tell.

Now using 5.5.2. Still no problems attributable to PHPUnit.
