    /** encapsulates a css::logging::XLogger

        The class silences several (unlikely) errors which could potentially happen
        when working with a logger. Additionally, it provides some convenience methods
        for logging events.

        You can use this class as follows
<pre>
    EventLogger aLogger( xContext, sLoggerName );
    ...
    aLogger.log( LogLevel::SEVERE, sSomeMessage );
    aLogger.logp( LogLevel::CONFIG, "MyClass", "MyMethod", sSomeMessage, SomeParameter1, SomeParameter2, SomeParameter3 );
</pre>

        The <code>log</code> and <code>logp</code> calls support up to 6 parameters, which can be of
        arbitrary type. For every parameter, there must exist a function <code>convertLogArgToString</code>
        which takes an argument of the respective type, and returns a string.

        After a parameter has been converted to a string using the above mentioned
        <code>convertLogArgToString</code> function, a placeholder $1$ (resp. $2$ resp. $4$ ...)
        in the message will be replaced with this string, and the resulting message will be logged.
