slurp! mechanism

[jayjlawrence]

You might find my slurp! method handy - see README.md for example of how it will automatically slurp a spreadsheet by using the sheet names to find the model class. If it can't find it then it will warn and move on to the next.

I added a couple of options that should be non-invasive to import! ... :delete and :sheet. You may want to have import! look for a sheet name based on the model class or table name ... or just leave with selecting the first sheet of the workbook.

Thanks!

2.Trace said he was thrilled with the pull request to add more functionality, ie slurp, but he hadn't merged it because there were no associated tests for the new code. In other words, there is no new block in the spec,
https://github.com/tracedwax/importeroo/blob/master/spec/importeroo/importer_spec.rb
3.I'm going to see if I can add a test. Perhaps part of it needs a new fixture, if the existing excel file doesn't have multiple sheets.

Great to see the feature is appreciated!

DOC: Previously, only the first worksheet in the spreadsheet would be input. Now with Slurp, each worksheet is output as a class object.

@jayjlawrence , I got doing other things, but it seems I probably should put this on a VM since there are so many dependencies. Can you quickly tell me what you mean when you say classes are created for each tab? I'm not finding the code clear. Where does the class that is generated output? How do you use it? Is that code pushed up here in this commit or am I missing something? Thank you!
