🐛 Bug

Compiling against the C++ API on macOS using GCC-9.3, and cmake seems to use a bad flag:
... -fopenmp -D_GLIBCXX_USE_CXX11_ABI= -std=c++14 ... -- note how it "blanks out" the _GLIBCXX_USE_CXX11_ABI variable. This causes the compiler to fail in the stdlib:

/usr/local/Cellar/gcc@9/9.3.0/include/c++/9.3.0/x86_64-apple-darwin18/bits/c++config.h:273:27: error: #if with no expr

Support Series.median()

Numpy has a way to rotate matrices by increments of 90 degrees using their rot90 method that uses transposes and flips.

There is a transpose method for Tensors, but no way of flipping the Tensor that I see.

Is there a way of properly rotating a Tensor/Dense currently, other than through manual iteration over the

The Scaladoc should be similar to numpy's API reference
