TODO:
---------------
Peter's work list:
2)- Precision conversion and sort out localConvert <--
3)- Remove DenseVector, DenseMatrix; Use Eigen instead. <-- started
4)- Binary I/O speed up & x-strips
-- Profile CG, BlockCG, etc... Flop count/rate -- PARTIAL, time but no flop/s yet
-- Physical propagator interface
-- Conserved currents
-- GaugeFix into central location
-- Multigrid Wilson and DWF, compare to other Multigrid implementations
-- HDCR resume
Large item work list:
1)- MultiRHS with spread out extra dim -- Go through filesystem with SciDAC I/O
2)- Christoph's local basis expansion Lanczos
3)- BG/Q port and check
4)- Precision conversion and sort out localConvert <-- partial
- Consistent linear solver flop count/rate -- PARTIAL, time but no flop/s yet
5)- Physical propagator interface
6)- Conserved currents
7)- Multigrid Wilson and DWF, compare to other Multigrid implementations
8)- HDCR resume
