// This logically belongs in the static constructor (as it only needs
// to be done once), except for one thing: if the .config file has a
// syntax error, .NET throws a ConfigurationException. If we read the
// .config file in the static ctor, we throw a ConfigurationException
// from the static ctor, which results in a TypeLoadException. Oops.
// Reading the .config file here will allow the static ctor to
// complete successfully, allowing us to throw a normal
// ConfigurationException should the .config file contain an error.
//
// There are also some ordering issues.
//
// DiagnosticsConfigurationHandler doesn't store values within TraceImpl,
// but instead stores values it reads from the .config file within a
// TraceImplSettings object (accessible via the TraceImplSettings.Key key
// in the IDictionary returned).
