MAHOUT-1990 [WIP] Add Multilayer Perceptron
### Purpose of PR:
Implements multi-layer perceptron style neural network
Also introduces some SGD functionality (namely learning strategies) (will,
doesn't yet)
Also introduces classifier trait
### Important ToDos
Please mark each with an "x"
- [x] A JIRA ticket exists (if not, please create this
first)[https://issues.apache.org/jira/browse/ZEPPELIN/]
- [x] Title of PR is "MAHOUT-XXXX Brief Description of Changes" where XXXX
is the JIRA number.
- [ ] Created unit tests where appropriate
- [ ] Added licenses correct on newly added files
- [x] Assigned JIRA to self
- [ ] Added documentation in scala docs/java docs, and to website
- [ ] Successfully built and ran all unit tests, verified that all tests
pass locally.
Does this change break earlier versions?
**yes** refactored linear regression to new sub-package, and created
nonlinear package.
Is this the beginning of a larger project for which a feature branch should
be made?
... possibly, but I think I will have it all working in short enough order
that it can stay on mine- however I am open to this idea if someone else wants
to chip in.

> Key: MAHOUT-1990
> URL: https://issues.apache.org/jira/browse/MAHOUT-1990
> Project: Mahout
> Issue Type: Improvement
> Components: Algorithms
> Affects Versions: 0.13.2
> Reporter: Trevor Grant
> Assignee: Trevor Grant
>
> Following strategy
> It should-
> 1. implement incoreMLPs which can be 'plugged together' for purposes of back
> propegation (this makes for easy extension into more complex networks)
> 2. implement a common distributed MLP which maps out incoreMLPs and then
> averages parameters
> 3. regression and classifier wrappers around the base MLP to reduce
> duplication of code
> 4. would be nice to make distributed and incore neural network 'trait' for
> consistent API across all future neural networks.
