Granular error/warning configuration?

[roll]

Overview

From an user feedback:

can the schema validation differentiate between errors and warnings? For example, if had to be a float, but also is normally between 0-1. We would issue an error if var="text", and a warning if var=2.3.

@roll on this one, for the particular case, I think the user is not aware of the constraints at all, and therefore, an error on var=2.3 would also work. cc @danfowler

For this reason, I think this is a pilot issue, and not necessarily (or, not yet) a goodtables issue.
