0a1285405c [gfs] Lattice fourier, multivar G, curry, tail
- Add Fourier for lattice.
  - Add regular_bz_mesh, cyclic_lattice, and their FFT.

- rm freq_infty.
- The gf can now be evaluated on a tail_view, which result in composing the tail.
- Fix the following issue :
  g(om_) << g(om_ +1)
  will recompose the tail correctly.
- TODO : TEST THIS NEW FEATURE IN DETAIL.

- Work on singularity for G(x, omega)

 - Separate the factory for singularity from the data factory in gf.
 - overload assign_from_functoin (renamed).
 - Fix singularity_t and co in the gf (const issue).

- Clean tail, add tail_const_view
 - add m_tail for x -> tail on any mesh
 - test curry + fourier works on k

47cb8a03f7 [arrays] Important changes in implementation.
- Simplify group_indices
  - Only for C ordered, remove complex compile time.
  - Could be generalized to non C ordered, but no need.
- Fix slice for custom orders.
- Generalize the group_indices for the custom order.
- Add c_ordered_transposed_view (useful ?)
- Improve slice, special for ellipsis (quicker).
- Simplify TraversalOrder
- Assignement. Specialize one case for speed.
- use FORCEINLINE in foreach, according to speed test for clang
- add one speed test
- Modify iterators for better speed.
- along the lines decided for the foreach
- update doc.

fa07abbea9 [gfs] Singularity as an explicit template parameter
- change the underlying data : do not flatten the linear indices of the
  mesh into a single index, keep a higher dim array.
- easier for various places, and necessary for g(nu,nu').
- work on several 2 part. containers.
- add default target (may not be always matrix_valued)

38cfef4e9f Implement mpi lib (1). Array, generic, base, vector
- Implement the basic structure of the mpi lib
  and specialization for arrays, basic types, std::vector
- adapted the array class for the lazy mpi mechanism
- pass tests on arrays :
   - scatter, gather on array<long,2> array<complex,2>, etc...
   - broadcast
- several files for readibility
- the std::vector coded but not tested.
- generic mecanism implemented and tested (mpi_generic test)
- added several tests for the mpi lib.
- TODO : more tests, doc...

e6234ed3d5 Fix #122
- the conj_ function was not written properly
  (T is a ref, the trait is_complex was not returning true).
- a simpler version is clearly better !

dcbdd5bc54 Clean the eigenelements tests.

  with same lib code.

9265c2db7f Fix #119
- Cleaned of the eigensystems computations (worker is simpler, decision
  at runtime, etc..).
- Fix #119 : When the matrix is in C order, the fortran lapack
  sees in fact its conjugate, so we need to conjugate the eigenvectors at the end.
  NB : not true if the storage order of the matrix is already fortran of course.

4af1afbdaf hdf5 : clean up
- For users : only change is :
   H5::H5File in apps. to be replaced by triqs::h5::file, same API.

- using only the C API because :
   - it is cleaner, better documented, more examples.
   - it is the native hdf5 interface.
   - simplify the installation e.g. on mac. Indeed, hdf5 is
     usually installed without C++ interface, which is optional.
     E.g. EPD et al., brew by default.
     Also the infamous mpi+ hdf5_cpp bug, for which we have no clean solution.

- clean the notion of parent of a group. Not needed, better iterate function in C LT API.
- modified doc : no need for C++ bindings any more.
- modified cmake to avoid requiring CPP bindings.

- Clean the implementation of the random_generator
- update the documentation
- update to the new python wrapper (could not be done with the previous
  version, because of lack of move constructor).

4789dccda6 parameters : small details
- an include missing on OS X
- change serialization in the general case where hdf5 can be used,
  (version of hdf5 high enough) to use only one buffer,
  not a buffer per field.
- put back the mpi_param example.

af084f5d59 parameters & wrapper
- new parameter class :
  parameters are viewed as form, built in C++, and filled in C++/python.
  Each field of the form as a precise C++ type (erased using standard techniques).
  First tests ok, to be reread/checked.

  TODO : serialization is commented. Lead to long compilation time & large code
  due to boost::serialization. Use h5 when possible.

- wrapper :
  - separated the converters of the wrapped type in the TRIQS library
  - necessary for parameters (it used outside an .so) and potentially
    other codes, outside an .so module

3aa380ba9d Fixed abs bug in bravais_lattice + added method
When constructing the last unit vector in 2D, the sanity check was wrong because of usage of abs instead of std::abs.

Added method energy_on_bz_path_2 that returns the energy *matrix* at each k point on a given path instead of the eigenvalues of this matrix. The name of the function should be changed (to energy_matrix_on_bz_path?)

Renaming energies_on_bz_path_2 to energy_matrix_on_bz_path

73d81cc55a gf: correct bug in matsubara_freq mesh point
- bool at_end() for a mesh point means AFTER the last point ,
as end in STL. It was not correct ( +1 missing).
- also the at_end was not computed in the mesh product.
- it slightly changes the test_fit_tail --> just changed the output.
--> did this bug affect other functions/codes ?
