Add in-line error component

[esscott]

As a data entry person, I want to see any errors associated with a specific data point displayed directly in-line with an error code and description of what's wrong, so that I can easily identify what needs correcting and whether it's a typo that I can fix at my desk or something that needs to be checked in the field.

Use Storybook #36 to create and test in-line error component without proper backend.

Seems like the error message was added in this PR: #71

It's not as a separate component though. So the remaining work on this issue would be to move it into a separate component.
