> Detects if a file exists and returns the resolved filepath.
## Install

```
## API
### [detect](index.js#L33)
Detect the given `filepath` if it exists.
**Params**
* `filepath` **{String}**: filepath to detect.
* `options` **{Object}**: Additional options.
* `options.nocase` **{Boolean}**: Set this to `true` to force case-insensitive filename checks. This is useful on case sensitive file systems.
* `returns` **{String}**: Returns the detected filepath if it exists, otherwise returns `null`.
**Example**
```js
var res = detect('package.json');
console.log(res);
//=> "package.json"
var res = detect('fake-file.json');
console.log(res)
//=> null
```
## Case sensitive file systems
When using the `nocase` option, this library will attempt to detect the filepath with the following methods:
1. Try to read all files in the `filepath` using `fs.readdirSync`. If successful and `filepath` is a directory, return the `filepath`.
2. Try to read all files in the `filepath`'s directory using `fs.readdirSync`. If successful, do case insensitive comparasions of the `filepath` to the files in `filepath`'s directory.
