Detailed Description

Abstract class for global writers.

Author

Marco Vignati

Global writers are managed by the QGlobalWriterDispatcher class that
takes care of file opening and closing when it is necessary.

Global writers have to prepend an "L" to their names as they are
loadable plugins. In the implementation file the following macro
not followed by semicolon have to be used in order to generate the
code needed by the QGlobalRWFactory:

REGISTER_GLOBAL_WRITER(clazz, ext)

where clazz is the clazz name without "" and ext is the file extension
that identifies the file types that this writer can manage.
Exemplum for the text file writer LMyGlobalWriter:

REGISTER_GLOBAL_WRITER(LMyGlobalWriter,".txt")
