Feature/procfs module

Reference to #9 
One should include a support for the short and long strings that reflect the unit using parameters enumerations like:
```
object Status extends Enumeration {

  case class StatusVal(code: Int, name: String, description: String) extends Val

  val OK = StatusVal(1, "Ok", "Okay")
  val NOT_OK = StatusVal(1, "Not Ok", "Not Okay")
  val BAD = StatusVal(1, "Bad", "Run for your life")
}
```
