The importedNames arg values come from state.opts. We might also want to set the imported names to state.importedNames

I think this should be node.source.value.indexOf('emotion') !== -1 so it includes emotion, react-emotion, preact-emotion and any other runtimes people create.

Can you change this from default to styled

| names.default = singleImport.local.name | ||

This can be done with state.file.metadata.modules.imports in the Program enter visitor.

Thanks for the suggestion. Was able to remove parseImports and the ImportDeclaration visitor.

styled doesn't exist in emotion. It's only in react-emotion and preact-emotion.

| import styled, { css } from "react-emotion"; |
Basically this is a POC that proves that this works without extra configuration. Breaks no existing tests. Only works for `styled` calls. ```js import lol from 'emotion'; lol`color:blue`; ```
Set importedNames on state and merge with babel opts.
* Remove ImportDeclaration visitor * Remove parseImports * Move import naming logic to `Program`

Built on top of lint-fix changes (#289) -- compare between these two branchesWhat:
Solves #267 by implementing a solution that will use the default import name instead of sticking only to
styled.in short, this works:
Why: See #267
How:
Modified the visitor to also visit ImportDeclarations. Then cache the values of any
import whatever from 'emotion'in an object for later use when looking forstyledcalls.Checklist:
These need work. This is just a POC. There definitely needs to be more tests.
