 ## JsonExtensions
 For both of these extension methods I'm using the `Newtonsoft.Json` library. I'm planning on migrating to `System.Text.Json` as soon as it is viable. Right now, Newtonsoft is easeir to serialize enums to thier ToString() value rather than index, and to deserialize the same. For example, by default - an enum is serialized to the index of the value. So an enum with (High, Med, Low) values would otherwise be serialiezed to a 2, instead of to "Med". Serializing to "Med" is my prefered behavior. I will continue to evailuate `System.Text.Json` against these unit tests and most likely migrate at some point.
