Updated sbt to 0.13.5
Merge remote-tracking branch 'origin/devel' into develop

* origin/devel:
  Added minIterations to FirstOrderMinimizer and SGD
Merge pull request #285 from gabeos/feature/algebra

Feature/algebra
fix for #286
Merge remote-tracking branch 'scalanlp/master'
Use a case class for SVD instead of a tuple
case classification of QR/eig/etc
generification of several FeatureVector ops
transpose multiplicaiton for feature vectors
remove scalalogging
Merge pull request #288 from mengxr/remove-scalalogging

remove scalalogging from dependencies
improved the interface for checking convergence in the optimizers.

You can now ask for min.minimizeAndReturnState instead, and that
will give you a state object with a .convergenceReason

fixes #250
Merge remote-tracking branch 'scalanlp/master'
Merge branch 'master' into develop

* master: (93 commits)
  we should really be calling this 0.9-SNAPSHOT
  axpy(a, fv, sv)
  fixes #283
  CSC/FV mult, improvements to DM/FV mult
  fixes #282
  reduce the amount of specialization, should shrink jar sizes
  pushing for re-test
  Fixed up some issues, added optimization space.
  lower drop count, tests still seem to pass and are faster
  add unit tests
  Fixed errant Double dependency in lift op, changed test to int to ensure it's not using DM's dv * dm, which is specialized for blas with Double.
  Updated lift op for dv * dv.t (reduced generics) and added test
  Added implicit lifting OpMulMatrix.Impl2[DenseMatrix[V],DenseMatrix[V],DenseMatrix[V]] to work with DenseVector * DenseMatrix. This enables DenseVector * Transpose[DenseVector] using the implicit that lifts Matrix operations to work with Transposed DenseVectors.
  transition probability now added
  fixed return type of MutableRestrictedDomainTensorField
  fixed DenseVector and SparseVector to return a MutableRestrictedDomainTensorField
  removed an empty line...
  log1p is preferable
  Refactored Matrix Norms to object
  Added TensorFields (which allow QuasiTensor operations) and RestrictedDomainTensorFields (which allow zeros, dim, and tabulate)
  ...
