Rework of WilsonFlow class
Fixed logic error in smear method where the step index was initialized to 1 rather than 0, resulting in the logged output value of tau being too large by epsilon
Previously smear_adaptive would maintain the current value of tau as a class member variable whereas smear would compute it separately; now both methods maintain the current value internally and it is updated by the evolve_step routines. Both evolve methods are now const.
smear_adaptive now also maintains the current value of epsilon internally, allowing it to be a const method and also allowing the same class instance to be reused without needing to be reset
Replaced the fixed evaluation of the plaquette energy density and plaquette topological charge during the smearing with a highly flexible general strategy where the user can add arbitrary measurements as functional objects that are evaluated at an arbitrary frequency
By default the same plaquette-based measurements are performed, but additional example functions are provided where the smearing is performed with different choices of measurement that are returned as an array for further processing
Added a method to compute the energy density using the Cloverleaf approach which has smaller discretization errors
Added a new tensor utility operation, copyLane, which allows for the copying of a single SIMD lane between two instances of the same tensor type but potentially different precisions
To LocalCoherenceLanczos, added the option to compute the high/low eval of the fine operator on every restart to aid in tuning the Chebyshev
Added Test_field_array_io which demonstrates and tests a single-file write of an arbitrary array of fields
Added Test_evec_compression which generates evecs using Lanczos and attempts to compress them using the local coherence technique
Added Test_compressed_lanczos_gparity which demonstrates the local coherence Lanczos for G-parity BCs
Added HMC main programs for the 40ID and 48ID G-parity lattices
