Constants for IANA message headers (http, mime, mail, etc)

Reason this exists

Wouldn't it be better to retrieve Http header information using a Http header constants, like this request_headers.get(http.REFERER). Constants such as http.REFERER for the string Referer reduces typos, and having to remember the exact spelling for Http headers.

This library does the following:

1. Refers to the list of headers registered with IANA: https://www.iana.org/assignments/message-headers/message-headers.xhtml . The definitions are available for download, as CSV files. These files are present in the references folder.
2. Generates the headers, under the headers package, using the locally available CSV references files.

Usage

from headers import http, mime

...
request_headers.get(http.HOST) # provides access to the 'Host' header from the request
mail_headers.get(mime.Content_Location)
...
