Initial value:

{R"MODES_HELP(
        - 'C': Classic Krylov subspace method with the standard Lanczos
               implementation. Implemented in classic_krylov.h, not
               available in syten-krylov.
        - 'K': New standard Krylov subspace method with the standard Lanczos
               implementation ordering. Can make use of the same solver and
               orthonormalisation policies as the tensor networks-oriented
               Krylov methods below. Implemented in standard_krylov.h
        - 'D': Davidson method without preconditioning (essentially
               Lanczos). Only supported for eigenvalue problems, not
               exponentials.)MODES_HELP"}

Static string describing the available modes.
