Node Module for reading [Control Group][cgroup] usage stats


Currently this reads the following data:
 - [memory.usage_in_bytes][memory] - current usage for memory
 - [memory.max_usage_in_bytes][memory] - max memory usage recorded
 - [cpuacct.stat.user][cpuacct] - time spent by tasks of the cgroup in user mode
 - [cpuacct.stat.system][cpuacct] - time spent by tasks of the cgroup in kernel mode

**This only works on Linux operating systems**

## Usage

```javascript
var cgroupStats = require('cgroup-stats');

cgroupStats(function (error, data) {
    console.log(data.memory.usage_in_bytes);
    console.log(data.memory.max_usage_in_bytes);
    console.log(data.cpuacct.stat.user);
    console.log(data.cpuacct.stat.system);
});
```
