Immutable.Net 2.0

[mattnischan]

This issue will hold a general list of tasks and/or considerations for the next major Immutable.Net release:

• Change Immutable and ImmutableBuilder to value types to avoid double allocating with each modify call
• Create a shared interface between Immutable and ImmutableBuilder
  • Use generic method constraints to avoid boxing?
• Update to multi-target frameworks
  • Improves dependency graph for library consumers
• Investigate creation of an API where the object itself can serve as the Immutable, something like:

public class SomeClass : ImmutableClass<SomeClass>
{
    public string SomeString { get; }
}

var someInstance = new SomeClass { SomeString = "someValue" };
var modifiedInstance = someInstance.Modify(x => x.SomeString, "modifiedValue");

We would be very interested in the point about the ImmutableClass<SomeClass> construct. Any pointer as to how? I might be able to see if I can contribute the feature.
