## The Importance of Being Reloadable
`mount` has start and stop functions that will walk all the states created with `defstate` and start / stop them
accordingly: i.e. will call their `:start` and `:stop` defined functions.

maintain the start order for all the `defstates`.
The "start" order is then recorded and replayed on each `(reset)`.
