v0.3.1

Bugfixes for macros:

• All tests which checked for proper types of fields did not work properly when the fieldname was encapsulated in extra double quotes. In those cases the test would always pass, even if the type of the field was incorrect.
• The test type_integer only allowed the int type for SQL Server, it now also accepts bigint as type to be compatible with the to_integer macro.

Other updates:

• The documentation and internal code have been updated to use ‘field’ instead of ‘attribute’. Note: Also the test attribute_length was renamed to field_length.
• A file with third party licenses was added
