Detailed Description

The Tagging class provides quick methods to access and modify the tags associated to the files.

Note: This class follows a singleton pattern and it is thread safe, by creating a new instance for each new thread that request access to the singleton. All of the internal instances are self-handled and destroyed when the application quits.

Graphical interfaces are provided which implement most of this class functionality and can be quickly used:
