# singleton-uuid

Create a [naive] singleton UUID per machine and per session.

`singleton-uuid` will generate a valid V4 `uuid` the first time the module is called on a machine. When is called for the first time a cache file will be generated and subsequent calls will return the same UUID.

## Documentation

The function takes one argument. 

If this argument is a string, and the string is a valid UUID then the cache will be overwritten and subsequent call will use this UUID.

If the argument is a boolean- or any other type for that matter- then the cache will be refreshed returning a new UUID.

## Examples

```
var uuid = require('singleton-uuid')();
```
