copied local test settings (i think...)

I'm pretty sure there is an intended typo in the README as there exists no "_local_test.py.example" file in the dir
Is this an intended typo to trip it up? methinks so...
added some files to my gitignore...
added test for detect_book_id function (which does not currently exist)
another test for the detect_book_id function
another test for detect_book_id

in this test we check for the proper detection of a book id of an update version of a book, when that updated version has a bad book_id and the original book is in the system
added a test for the detect version function (which does not exist yet)
another test for the detect_version function

this test detects versions implied by "2nd edition" statement in the title of the book
another test for version detection (default version)

also an extra line!
oh yea! nothing better than copying a typo over and over... (fixed)
cleaning up some more typos
added a function for detecting the book's version
another typo, fixed
forgot the syntax of the xml updates, fixed...
updated this test to conform with the new expected book id standards
well, that was a bad typo that went undetected for a bit!
added a test for a "find book by isbn" controller
added a test to simulate expected problems with xml updates
added a detect_book_id function, returns the book id
added a "find book by ISBN-10" controller to find books given their ISBN code
