/**
* A logback converter to support an indent customer conversion specifier.
*
* Note that the {@link #convert(ILoggingEvent)} method simply returns a {@link String} with a single character based on the passed event's marker (if the marker is not recognised
* or no marker is present, a {@link String} with a single space character is returned).
*
* Actual indenting has not been implemented as it will affect trace performance. Using a suitable Boss trace filter it will be possible for Boss trace to format and indent as
* required anyway, hence indentation is not required by the service team.
