Detailed Description

A dummy structured logger.

This should be replaced by a fully functional logger from Profiler or similar.

The log output is structured using JSON or HTML format for easy parsing. Logging is split into sections

//Log output
{ // some initial state attributes
Log = [
{SectionName = "Section1",
Log = [
{SectionName = "Section1Child1"},
Log = [{ date = "year-mm-dd-hh:mm:ss", msg="log message", custom_entry_name="DataDump"}
,{ date = "...", msg="another message"}
]
]
}
,{SectionName = "Section2"
}
]
}

The logger also handles output which might go to a separate stream.
