/// This call is considerably faster than using reflection to perform the same job,

/// This type of constructor is particularly useful when it is known that a type that
/// implements a known interface takes a parameterised constructor. The follwing example

/// an attribute on the class. It has been agreed that the plugins will be able to accept
/// a configuration file's path as a constructor parameter, in order to initialise its
/// custom properties.
/// <example>
/// <code>
/// Attribute attr = Attribute.GetCustomAttribute(MyPluginAssembly, typeof(PluginImplementationAttribute));
/// Type t = attr.PluginImplentationType;
/// String path = MySettingsPath;
///
/// Latebound MyPluginInstance = new Latebound(t, path);
