 ## Usage
-Create a class and extend the type of the chainable class you require.
-Your class can have its own constructors and its own attributes of course !
-Respect the interface contract and override the job method.
-You need to override the start method also for the chain_Batch and chain_ScheduleBatch class
-The job method will contains your business logic. It can access the private attributes of your class (and the protected ones of the base class).
-If you need some extra interface to make you're code work, it is up to you to add them (Database.Stateful, Database.AllowsCallouts, etc).
-You're ready to chain ! 
-You do not need to override another method except if you really know what you're doing
