Fixed an issue with typespec #23 by @namjae

Allow guard functions to return a custom error tuple

Reverts previous version

A 'guard' word refers to the elixir guard check, which returns a boolean. In the case of 'machinist', the behaviour is to return the next state so that a cond should be a better word for this purpose

Add a new way to set from transitions. With this new feature we can group many from definitions with a same state.

 # ...
 transitions do
   from :locked, to: :unlocked, event: "unlock"
   from :unlocked do
     to :locked, event: "lock"
     to :opened, event: "open"
   end
   from :opened, to: :closed,   event: "close"
   from :closed, to: :opened,   event: "open"
   from :closed, to: :locked,   event: "lock"
 end
 # ...

• implemented macro Machinist.from/2 that expects a state and a block of to statements
