map context fields

**Mapping context fields.**

Could it be an idea to map context fields if 'mapping field does not exist'?

For example, if I map

> title title

And if EasyForm title does not exist => title = context.title

Some kind of checking, for title this works:

if "id" in mappings and mappings["id"]:
title_or_id = mappings["id"]
elif "title" in mappings and mappings["title"]:
title_or_id = mappings["title"]
elif context.title:
#use title or some other field
title = context.Title()
mappings["title"] = title
title_or_id = title
