Title: Sampler with Automatic Cross Validation support

Usage:
```
# Feature library gives us lots of features so we need proper
# regularization. Use "--reg_param X" (or -b X) multiple times and
# system will choose proper parameter with Cross Validation.
sampler.sampler_args: "-l 300 -s 1 -i 500 --alpha 0.1 --diminish 0.99 --reg_param 0.1 --reg_param 1 --reg_param 10"
```
