Monotonic Variable

Made this definition up myself. This is effectively a one way variable that starts off in one state and switches to another alternate state. It always starts off in a known state and during the period when it can be accessed by multiple threads it can only be switched to the other alternate state. This has repercussions for thread safe access to the variable with .NET. In certain cases, it can be that none is required. TODO: Explain in more detail.

Generally I use a boolean for my monotonic variable but it is not necessarily a boolean, I have used a reference type in a monotonic manner where the variable has a null reference to begin with, but at some point the reference is assigned.
