Added documentation for Webforms API
Merge pull request #17 from Zeitguys/master

Added documentation for Webforms API
Revise linkage
First scratch at a potential API
More form-field manipulations
clarify code to show field list is 0-indexed
Added static function option

Based on today's discussions, I have added another option, namely using functions in the global namespace rather than object instantiation.
Added field templates
Deprecated Option 2
Procedural functions return the underlying object
Cleanup, plus started some batch adding.
flipped form-id, field-id order in register_form_field
More batch field registration
Batch form field "capture" syntax
Update batch registration of fields based on feedback

Removed the contentious begin_add_form_fields() and end_add_form_fields(). Apparently the code "smelled" :)
Initial commit for work-in-progress
Delete index.php (the old one) and updated README.md
Deleted README.txt and added README.md
Fixed self::POST_TYPE in example.
2nd major commit of work-in-progress. Code still does not work, but too many changes to not have an off-site backup.
