[Enhancement] Add an attribute to exclude properties from nested objects.

[tstephansen]

Summary

I sometimes use ObjectDumper to create unit test data for my software. In some cases I am dumping an object that has many children (with children) and I want to exclude properties of these children. I know you can exclude properties of the object you're dumping but I don't see a way to do it for the object's children. I propose adding an [ExcludeFromObjectDumper] attribute that can be placed on the properties I want excluded from the dump. I have already made these modifications and added tests to support them in my fork of the project.

API Changes

Add an ExcludeFromObjectDumper attribute.

[System.AttributeUsage(System.AttributeTargets.Property)]
public class ExcludeFromObjectDumperAttribute : System.Attribute
{
}

In ObjectDumperCSharp.cs change the GetPropertiesToDump method:

var properties = type.GetRuntimeProperties()
    .Where(p => p.GetMethod != null && p.GetMethod.IsPublic && p.GetMethod.IsStatic == false &&
                p.GetCustomAttributes().All(c => c.GetType() != typeof(ExcludeFromObjectDumperAttribute)))
    .ToArray();

In ObjectDumperConsole.cs change the CreateObject method:

var properties = type.GetRuntimeProperties()
    .Where(p => p.GetMethod != null && p.GetMethod.IsPublic && p.GetMethod.IsStatic == false &&
                p.GetCustomAttributes().All(c => c.GetType() != typeof(ExcludeFromObjectDumperAttribute)))
    .ToList();

Intended Use Case

This proposal is useful if you are dumping objects that have nested objects and you want properties excluded from the nested objects.
