Simple PHP console output helper.
While using PHPUnit, you may want to output or debug your tests.
Normal echo/print_r/dump only outputs after PHPUnit's output, if at all.
Using ConsoleOutput will echo inline with PHPUnits output,
giving you a better context of your output/debugging.
Usage:
$this->consoleOutput = new ConsoleOutput();
$this->consoleOutput->showWarning('test showWarning');
test showWarning
