emulation classes have their own module
emulation classes have their own module

create the emulations module to make life easier and cleaner for everybody

refactor the NetemLossRandom() to LossRandom() with the intention to
use the same pattern for all the other emulation classes. this will
ultimately allow us to remove all those ugly eval() constructs,
and abstract validation and emulation command outputs to a single
parent class named _Emulation()
