Fixed wrong spectrum mismatch rbf construction in static interfaces
don't use ref'counted matrix in parameter example (fixing double free!)

* minor warning fixes
Fixed typo in MKL
Merge pull request #883 from iglesias/dev

minor fixes to compile VW examples
Speeded up MDS unit test
add unit test for sgvector's setters/getters
refactor parameters to use SGVector as dims (for future ndarray support)
include SGMatrixList.h instead of .cpp (Closes: #855)

Thanks bianjiang for the fix!
Mention of include fix in NEWS. Related to #855
changed create_merged_copy to work with multiple feature objects and added implementation for DenseFeatures
removed create_merged_copy example and added a test for combined features and dense features instead
Merge pull request #887 from karlnapf/master

added a new create_merged_features method
removed prints
corrected get_name
added simulate_h0 method to two-distribution based test statistics, which allows to sample the null hypothesis. This has to be handled in all methods that compute a statistic. Added handling for linear and quadratic time MMD. Changed the bootstrap_null method to use this flag
moved simulate_h0 flag to linear time MMD since in the case where data is stored, permuting it is easy: data is stored in one single feature object

better handling of null distribution sampling for linear time mmd
