> Get the file associated with a Sass import

This module replaces the Sass compiler's lookup algorithm for resolving a partial's path.

* Handles underscored/non-underscored partials,
partials with filenames, partials within subdirectories,
partials with the `.scss` in the name, all of it.

*Originally built for [Dependents](https://github.com/mrjoelkemp/Dependents#dependents)*

### Usage

```js
sassLookup({
  dependency: 'foo',
  filename: 'path/to/filename',
  directory: 'path/to/directory'
})
```

* `dependency`: The partial's name
  * If your sass file had `@import "foo";`, then `"foo"` would be the dependency name
* `filename`: The file importing the dependency
* `directory`: The location(s) of all sass files
  * A list of multiple directories is also supported for this argument.

Example:

```js
var sassLookup = require('sass-lookup');

sassLookup({
  dependency: 'variables',
  filename: 'app/styles/styles.scss',
  directory: 'app/styles'
}); // yields app/styles/variables.scss
```

* This assumes that the file `app/styles/styles.scss' has `@import "variables";`
and that all of the other sass files are located within `app/styles`.
* Would yield `app/styles/_variables.scss` if the partial had an underscored filename.
