Parser and Utilities for Java Command-Line Applications

This class enhances the features of the Apache Commons CLI library for parsing command-line parameters in a Java application by providing common-sense defaults and handlers for the following:

timestamped console logging
console output of help when no arguments are passed to your application
console output of version information, read from Jar manifest attributes
listener interface for options as they are parsed

Usage:

Create a CliParser at the top of the main() method, with a syntax String and options configured using .with() methods:

public static void main(String[] args)
    throws Exception
{
    CliParser cliParser = new CliParser("java -jar myapp.jar [OPTIONS] <Input File>")
        .withOption("r", "remove", true, "Remove something from somewhere")
        .withRequiredOption("a", "author", true, "Set an author (required)")
        ...

See all of the .with() methods in CliParser to know what to configure.

Call .parse(args) with application arguments and continue with the application only if it returns true:
```
if (cliParser.parse(args))
{
    //Main Application logic goes here
    ...
```
If parse(args) returns false, then the CliParser has already output an error message to the console along with the help message for the application.

If you configured a CliListener object when creating the CliParser, it will get called with every command-line option during the parse(args) call so that the application can configure itself with user-supplied options. If you did not configure a CliListener object, then you can read parsed user options with the getParsedValue(...) and getParsedValues(...) methods.
