v0.14.0

Rimu v0.14.0

Diff since v0.13.1

Breaking changes

• IDs for replicas and spectral states are swapped: replica ids defining
  the row in the matrix of state_vectors now are appended first and
  spectral ids second. If there is only a single replica, or a single
  spectral state, the respective ids are ommitted.
• Remove BoseFS2C, BoseHubbardMom1D2C, BoseHubbardReal1D2C. These models were moved to another package, see RimuLegacyHamiltonians.jl
• MPIData was removed - use PDVec instead.
• The submodule Rimu.RMPI was removed. The relevant remaining functions are exported at top level.

New features

• new module Rimu.InterfaceTests with functions
• test_observable_interface
• test_operator_interface
• test_hamiltonian_interface
• test_hamiltonian_structure
• ReducedDensityMatrix
• build_basis is faster (using threading) and can work on address type

Deprecations

• in keyword arguments to ProjectorMonteCarloProblem
  • maxlength deprecated, replaced by max_length
  • walltime deprecated, replaced by walltime
• lomc! now prints a deprecation warning

Internal changes

• fix random seeding of tests
• Documentation rework and docstring changes
• remove lomc! from most tests

Bug fixes

• normalisation in single_particle_density
