[IMPROVEMENT] Better handling of extended error source strings in classes "Formatter" (base class) and "HSE_v2_Formatter".
[IMPROVEMENT] Add input terminal for "Formatter" classes to the method "Create FileHandler.vi". The accessor methods are no longer needed.
[IMPROVEMENT] Fix the order of "Name" and "Level" terminals for the method "Create UserEventHandler.vi" in class "UserEventHandler". ATTENTION: this change breaks the code, and it's needed to rewire both terminals!
[IMPROVEMENT] Complement the functions palette with missing methods.

[FEATURE] Formatter classes to support flexible configuration of logger output. Special thanks to Paul O'Neill for this contribution!
[FEATURE] Formatter base class which supports the old logger format.
[FEATURE] HSE_v2_Formatter subclass supporting a new, improved for better readability.
[FEATURE] JSONLFormatter subclass suporting the JSON Lines format. Special thanks to Paul O'Neill for his contribution!
[IMPROVEMENT] Reverse call chain order for better readability (Main-VI -> Sub-VI -> Sub-Sub-VI).
[IMPROVEMENT] Set the error-in terminal for "ERROR.vi" and "CRITICAL.vi" to "required" to avoid logger VIs on the block diagram that never log anything.
[IMPROVEMENT] Clean up the error source string to remove unnecessary information and to remove line breaks.
[FIX] Several minor fixes.

Fixes

==============

Corrects the error handling of the log-helper VIs when the Logger is *not* initialized:

If there is no input error
* All helper VIs (DEBUG, INFO, WARNING, CRITICAL, ERROR) will output the "logger not initialized" error.

If there is an input error
* DEBUG, INFO and WARNING will output a duplicate of the input error (i.e. input-error passthrough)
* CRITICAL, ERROR will output a "logger not initialized error"

New in version 2.0.4
==============

- The FileHandler class flushes the file in configurable intervals (default is 5 seconds).

Changes/Fixes

==============

* The logger-VIs for DEBUG, INFO and WARNING do return an error caused by the logger first. An error on the "error in" terminal will be discarded in this (rare) case.
* The "FileHandler" does not flush every "Write to File" call. This improves the write performance.

New in version 2.0
=============

* All functions are accessible in the functions palette (Hampel Software Engineering>>HSE-Logger).
* The API is streamlined and follows the common conventions for LVOOP.
* With the improved API it's easier to develope own subclasses.
* All classes have getter/setter-methods accessible via property nodes.
* Re-organised the unit tests to use them with the HSE Release-Automation-Tools (RAT).
* Fixed a bunch of minor bugs and inconsistencies.

Fixes in version 2.0.1

==============

* Fixes a bug in Log.vi that prevented state changes in the handler object(s).

Incompatible API-changes
================

Compared to versions < 2.0.0 the methods for creating an object have changed.
It's very likely that your project will have a broken run arrow after updating
to version 2.0.0. In the common use case this affects only the creation of `Handler` objects
when initializing the HSE-Logger. For more information see the examples.
