Added object and make method for MutableLPVectorField
Merge branch 'master' into devel

* master:
  and test for DenseMatrix elementwise
  add element wise max(dv, s) etc.
  remove deprecated norm calls
  merging some more unnecessary imports
  Document, understand, organize
  minor import streamline
  activeSize/iterableSize doc comments from David
  Specialize breeze.linalg to Long as well
  deprecated NumericOps.norm() in favor of UFunc
  more refactoring and documentation
  Should norm be deprecated from NumericOps.scala?
  minor diff Storage.scala
  Storage.scala specialization?
  some more consistency
  Reading through code to understand data structures (edit documentation, variable naming consistency)
  Organize unneeded imports
  Add Long specialization to Storage (it is used in classes with Long specialization downstream)
Cleaned up make methods, removed unnecessary implicit arguments.
Switched deprecated .norm's to norm(...,..)
Merge pull request #297 from gabeos/devel

Cleaned VectorSpace make methods & updated deprecated norms.
compute correlation matrix - surprised this was missing.
Merge pull request #298 from stucchio/correlate

compute correlation matrix
covmat/correlation for sequence of vectors also
Merge pull request #299 from stucchio/correlate

covmat/correlation for sequence of vectors also
Linear regression
make it easier to specify presense of, or make use of specified work array
oops
added explicit type annotation
rename file
lasso regression. Computes sparsified least squares solutions.
oops - forgot to compute rSquared
idiomatic style
