What are stages?

Stages are the building blocks of CCIL. They are small non-interactive units of logic (Java POJOs) which take inputs and provide outputs. By themselves, nothing particular can be accomplished - some open files, others write input to a file handler etc. Organized in pipelines however, they can accomplish almost everything, as far as no interactivity is involved.

CCIL is designed to run at backend processing server without any human interaction.
