Breeze 1.0-RC2

[David Hall]

Hi everyone,

I've made a new release candidate. It includes a really important update where I accidentally used a (possibly) GPL-licensed dependency. (I think it's dual licensed MPL, but that's still not ideal.)  The new dependency has a nice BSD license.

It also contains:

* a more usable return type for LU decomposition (@ZacBlanco)

* a bug in matrix multiplies where the RHS arg is a Transpose[DenseVector]

* a new indirectSort algorithm that sorts parallel key and value arrays. Mostly an internal API. (Sergei Lebedev) 

* Fixed SBT incremental compilation of @expand macros.

* A fix to the DM/DM multiply for non-floating point types.

* the source is now Scalafmt'd (Sergei Lebedev)
