Allow for form cells in multiple sections
Make existing tests use new methods to set cells and sections
More specs for new section feature. Use addFormCells:atSection: in sample. Add resignFirstResponder method to BZGTextFieldCell so we can stub it in the tests
clean up code using a constant
Use two sections in the sample form
changes to readme for new multisection feature
readme formatting
Change more becomeFirstResponder calls
Remove resignFirstResponder call, since becomeFirstResponder handles it
These are already methods because UITableViewCell is a UIResponder
startRow reads better
memoize allFormCells
