Set up structure, phpDoc ini file, gitignore and gitmodules
- Split file off from wp-hook-documentor.

- Removed initial .gitignore

- Changes:
* Removed find_line_of_function_def() method in favour of is_within_function() method which provides more extensive information
* Added is_within_function() method
* Added is_within_method() method
* Added strip_comment_markers() method - needs more work
* Added additional DocBlock tag: @type
* Improved documentation
* CodeSniff for WP coding style standards

Currently working on get_nearest_comment() method
