Added draft implementation of Yamamoto's QR, not working yet due to sign factor nastiness
Got Yamamoto's 2D QR working, although the testing mechanism is not working in parallel (verified by comparing R by eye)
Fixed Yamamoto QR test completely and added benchmark
free extra buffer needed for gemm
Don't build ScaLAPACK-dependent components without ScaLAPACK
Yamamoto aggregation now works
Unstable QR approaches in progress (still debugging)...
Unstable panel routines are passing tests
Integrated unstable panel factorization into 2D QR
