Rails Generator for ETL installation

[OpenCoderX]

After gem installation via gem file and bundle install:

allow the use of a generator to install activewarehouse-etl to the rails app creating all necessary directories as well as stub files with comments for instructions and dummy data as place holders for real data.

1. user would run - 'rails g activewarehouse-etl:install'
2. generator would add etl connection to - database.yml
3. generator would create 'etl' directory in rails root
4. generator would generate stub .ctl.rb, .ebf.rb, common.rb files
5. user can run 'rails g activewarehouse-etl:control [CONTROL_NAME]' to generate new stub control file
6. user can run 'rails g activewarehouse-etl:batch [BATCH_NAME]' to generate new stub batch file

This generator would help ease and quicken installation for beginners. Ideally after the generators are run the user will just have to develop inside the control file and run the command 'bundle exec...'

One thing is that I'm currently trying to move activewarehouse away from Rails and ActiveRecord in general, toward a more agnostic approach where AR is still allowed of course, but not required. There is plenty of time before this will arrive though.

Let me think: maybe we could put this into some contrib repository? This is something that will be needed anyway, because many people have contributed eg transforms that are quite specific and should not be in the core, but are definitely worthwhile sharing around.

What do you think?
