add benchmark comparing performance of mappingufunc on matrix, vector
Update benchmark to avoid spending so much time inside implementation of ufunc.
benchmark now tracks both a simple and a harder ufunc
throw exception when building a matrix with invalid stride
add strided benchmark
Shave a few milliseconds off CanMapValues[DenseMatrix, ...] with a specialized strideless version
routine was previously building invalid matrix
oops
check that DenseMatrix hsa enough storage on creation, throw exception if not.
better way to do it
indent fix
took out this attempt at a fix
more sanity checks
unnecessary space
majorStride is now allowed to be negative, and has proper error checks.
add case to speed up transpose also, and unit test to mkae sure it works
Merge pull request #253 from stucchio/speedup

Small Speedup mapping ufuncs over DenseMatrix
