Extract New Class Refactoring Request

[TonyValenti]

Brief description:
Sometimes code has properties like this:

    public class Foo {
        public string M1_Value1 { get; set; }
        public string M1_Value2 { get; set; }
        public string M1_Value3 { get; set; }
        public DateTime M2_Value1 { get; set; }
        public DateTime M2_Value2 { get; set; }
        public DateTime M2_Value3 { get; set; }
    }

Which should, ideally, be code like this:

    public class Foo {
        public M1 M1s { get; set; } = new();
        public M2 M2s { get; set; } = new();
    }

    public class M1 {
        public string Value1 { get; set; }
        public string Value2 { get; set; }
        public string Value3 { get; set; }
    }

    public class M2 {
        public DateTime Value1 { get; set; }
        public DateTime Value2 { get; set; }
        public DateTime Value3 { get; set; }
    }

A refactoring should exist that enables this kind of conversion.

Languages applicable:
Both, but I only care about C#

Code example that the analyzer should report:
See above

Additional information:
This is identical to the "Extract Base Class" refactoring except the members should be wrapped into a child class instead of a base class.

It is OK if it simply moved the members and a subsequent refactoring would be used to rename them.
For example, after the first refactoring, you might have:

    public class Foo {
        public M1 M1s { get; set; } = new();
        public DateTime M2_Value1 { get; set; }
        public DateTime M2_Value2 { get; set; }
        public DateTime M2_Value3 { get; set; }
    }

    public class M1 {
        public string M1_Value1 { get; set; }
        public string M1_Value2 { get; set; }
        public string M1_Value3 { get; set; }
    }

Documentation requirements:
When this analyzer is implemented, it must be documented by following the steps at Documentation for IDE CodeStyle analyzers.
