/**
 * Class for handling console output.
 *
 * The ezcConsoleOutput class provides an interface to output text to the console. It deals with formating 
 * text in different ways and offers some comfortable options to deal
 * with console text output.
 *
 * <code>
 * // Create the output handler
 * $out = new ezcConsoleOutput();
 * 
 * // Set the verbosity to level 10
 * $out->options->verbosityLevel = 10;
 * // Enable auto wrapping of lines after 40 characters
 * $out->options->autobreak    = 40;
 * 
 * // Set the color of the default output format to green
 * $out->formats->default->color   = 'green';
 * 
 * // Set the color of the output format named 'success' to white
 * $out->formats->success->color   = 'white';
 * // Set the style of the output format named 'success' to bold
 * $out->formats->success->style   = array( 'bold' );
 * 
 * // Set the color of the output format named 'failure' to red
 * $out->formats->failure->color   = 'red';
 * // Set the style of the output format named 'failure' to bold
 * $out->formats->failure->style   = array( 'bold' );
 * // Set the background color of the output format named 'failure' to blue
 * $out->formats->failure->bgcolor = 'blue';
 * 
 * // Output text with default format
 * $out->outputText( 'This is default text ' );
 * // Output text with format 'success'
 * $out->outputText( 'including success message', 'success' );
 * // Some more output with default output.
 * $out->outputText( "and a manual linebreak.\n" );
 * 
 * // Manipulate the later output
 * $out->formats->success->color = 'green';
 * $out->formats->default->color = 'blue';
 * 
 * // This is visible, since we set verbosityLevel to 10, and printed in default format (now blue)
 * $out->outputText( "Some verbose output.\n", null, 10 );
 * // This is not visible, since we set verbosityLevel to 10
 * $out->outputText( "Some more verbose output.\n", null, 20 );
 * // This is visible, since we set verbosityLevel to 10, and printed in format 'failure'
 * $out->outputText( "And some not so verbose, failure output.\n", 'failure', 5 );
 * </code>
 *
 * For a list of valid colors, style attributes and background colors, please 
 * refer to {@link ezcConsoleOutputFormat}.
 *
 * ATTENTION: Windows operating systems do not support styling of text on the
 * console. Therefore no styling sequences are generated on any version of
 * this operating system.
 * 
 * @property ezcConsoleOutputOptions $options
 *           Contains the options for this class.
 * @property ezcConsoleOutputFormats $formats
 *           Contains the output formats.
