version updated

2020-01-14 Version 5.68

Bug fixes: 

* SEVERE bug corrected in observe; see mailing list for details;

in BlockOffDiag.h::toSparse (Thanks to Max, Jacek, Ed)

* HubbardAncilla: c <---> cdagger

* Recovery: modalStruct restart fix

* Precision -p flag is now honored by all output (Thanks to Bradraj)

Scripts

* procOmegas will NOT do Fourier if -X is given to it. (Thanks to Rahul)

TestSuite

* 3511 is now shorter

* postCi can compare complex matrices

New features:

* Custom operators can now be defined in input file;

operators starting with _ are tracked

* Cheby: can now correct vectors, and accepts

ChebyshevCorrectVector= awesome predicate to

control when to correct (Thanks to Alberto)

* ChemicalH work, but not working yet (Alberto)

* CorrectionVectorAction supports complex correction vector

when useComplex is in use; we need to make sure this

does not interfere with RIXS KrylovTime experimental feature...

(Rahul, Alberto)

New Models

* GaugeSpin model to test ChemicalH features (not ready yet)

Engine work

* ModelLinks --> term.push modified API

* OperatorsCache class added, and transposed operators in

their own class

* BasisWithOperators templated on Basis now.

* ReducedOperators deleted

* Apply Factors deleted, along with other SU(2) stuff

* KroneckerDumper has been unhooked (is anyone using it?)
