dependency info
LICENSE and NOTICE policy is explained here:
http://www.apache.org/dev/licensing-howto.html
http://www.apache.org/legal/3party.html
This leads to the following changes.
First, this change enables two extensions to maven-shade-plugin in assembly/ that will try to include and merge all NOTICE and LICENSE files. This can't hurt.
This generates a consolidated NOTICE file that I manually added to NOTICE.
Next, a list of all dependencies and their licenses was generated:
`mvn ... license:aggregate-add-third-party`
to create: `target/generated-sources/license/THIRD-PARTY.txt`
Each dependency is listed with one or more licenses. Determine the most-compatible license for each if there is more than one.
For "unknown" license dependencies, I manually evaluateD their license. Many are actually Apache projects or components of projects covered already. The only non-trivial one was Colt, which has its own (compatible) license.
I ignored Apache-licensed and public domain dependencies as these require no further action (beyond NOTICE above).
BSD and MIT licenses (permissive Category A licenses) are evidently supposed to be mentioned in LICENSE, so I added a section without output from the THIRD-PARTY.txt file appropriately.
Everything else, Category B licenses, are evidently mentioned in NOTICE (?) Same there.
LICENSE contained some license statements for source code that is redistributed. I left this as I think that is the right place to put it.

Continue our discussions from https://github.com/apache/incubator-spark/pull/575
This PR is WIP because it depends on a SNAPSHOT version of breeze.
Per previous discussions and benchmarks, I switched to breeze for linear algebra operations. @dlwh and I made some improvements to breeze to keep its performance comparable to the bare-bone implementation, including norm computation and squared distance. This is why this PR needs to depend on a SNAPSHOT version of breeze.
@fommil , please find the notice of using netlib-core in `NOTICE`. This is following Apache's instructions on appropriate labeling.
I'm going to update this PR to include:
1. Fast distance computation: using `\|a\|_2^2 + \|b\|_2^2 - 2 a^T b` when it doesn't introduce too much numerical error. The squared norms are pre-computed. Otherwise, computing the distance between the center (dense) and a point (possibly sparse) always takes O(n) time.
2. Some numbers about the performance.
3. A released version of breeze. @dlwh, a minor release of breeze will help this PR get merged early. Do you mind sharing breeze's release plan? Thanks!
