- Commit title implies possible Xilinx Vivado HLS 2019.1 support, thus support
for e.g. all USRP Series 3 from Ettus.
- Add a new CORDIC version, Rom based and meta-programmed via CMake
features, to be even compiled with earlier GCC (not quite tested, but
by changing constexpr to const and using gcc 4.6 -sdt=c++0x, it
worked).
- Class name modified, to be more explicit.
