1ecec0b933 gfs: Fix bug in imfreq with <0 freq.
- there was a confusion in gf imfreq, in the new case
where freq can be <0 (non real gf, or for product gf).
- index: is the matsubara n, as in the struct matsubara_freq
  index can be >0 or <0
- linear_index : is the shift from the 0. It is always >0.
  Fixed function to compute it.

- Also changed the construction of mesh_point in the generic iterator.
  Before, was constructed with a mesh point of index 0
  Now, added a new constructor on mesh_point_t, just taking the mesh
  which construct the *first* mesh_point.
  Fixed linear, discrete, product accordingly.
  Added to the documentation of the concepts of gf.

9ce291d640 gf: update gf imfreq for g( om - nu) case
DRAFT : to be tested further...

- update gf<imfreq>
- write a specific mesh for matsubara frequencies
- now the cast series is :
  mesh_pt --> matsubara_freq --> complex<double>
- matsubara_freq is just the matsubara frequency
- arithmetic of the mesh_pt casted to matsubara_freq
- arithmetic of matsubara_freq is casted to complex, except + and -,
  which are kept as matsubara_freq.
- evaluator now accept : int, mesh_pt, and matsubara_freq
  for matsubara_freq : for negative omega, use conjugation
  for omega outside windows, evaluate the tail on omega.
- as a result : g( om - nu) where om, nu are 2 meshes points,
  is the extrapolation outside the grid if necessary.
- updated tests
- added evaluation for tail.

39edb2f846 [API change] gf : factories -> constructors
- Make more general constructors for the gf.
  gf( mesh, target_shape_t)
- remove the old make_gf for the basic gf.
- 2 var non generic gf removed.
- clean evaluator
- add tensor_valued
- add a simple vertex test.
- clean specialisation
- Fix bug introduced in 1906dc3
- forgot to resize the gf in new version of operator =
- Fix make_singularity in gf.hpp

- clean resize in operator =

- update h5 read/write for block gf
  - changed a bit the general trait to save *all* the gf.
  - allows a more general specialization, then a correct for blocks

- NOT FINISHED : need to save the block indice for python.
  How to reread ?
  Currently it read the blocks names and reconstitute the mesh from it.
  Is it sufficient ?

- clean block constructors

 - block constructors simplest possible : an int for the number of blocks
 - rest in free factories.
 - fixed the generic constructor from GfType for the regular type :
   only enable iif GfType is ImmutableGreenFunction

- multivar. fix linear index in C, and h5 format

  - linear index now correctly flatten in C mode
    (was in fortran mode), using a simple reverse of the tuple in the folding.
  - fix the h5 read write of the multivar fonctions
   in order to write an array on dimension # variables + dim_target
   i.e. without flattening the indices of the meshes.
   Easier for later data analysis, e.g. in Python.

- merge matrix/tensor_valued. improve factories

  - matrix_valued now = tensor_valued<2>
    (simplifies generic code for h5).
  - factories_one_var -> factories : this is the generic case ...
    only a few specialization, code is simpler.

- clef expression call with rvalue for *this
- generalize matrix_proxy to tensor and clean

 - clean exception catch in tests

  - exception catching catch in need in test
    because the silly OS X does not print anything, just "exception occurred".
    Very convenient for the developer...
  - BUT, one MUST add return 1, or the make test will *pass* !!
  - --> systematically replace the catch by a macro TRIQS_CATCH_AND_ABORT
    which return a non zero error code.
   - exception : curry_and_fourier which does not work at this stage
   (mesh incompatible).

- gf: clean draft of gf 2 times
  - comment the python interface for the moment.
  - rm useless tests

a5938a8d9e Fix arithmetic of mesh_points in gf
- the arithmetics of the gf mesh_points :
the forwarding of the second argument was missing,
leading to subtle bugs e.g. in  (in matrix case) :

  deltaw(iom_) << iom_ * gw.singularity()(-1) + gw.singularity()(0) - gw(iom_);

because the partial evaluation of the expression introduced a dangling const matrix_view &
instead of moving the temporary matrix_view into the final matrix expression template.

f4444f3b49 Revert a wrong fix in expression template for gf
This reverts the part of the commit 1906dc30a5
which introduced modifications in the expr templates of the Green's
functions. The commit had introduced some bugs and this revert
removes them (the expr templates will be taken care of fully in later
commits). This is a temporary fix for issues #18 and #25.

f0dfabff38 Change tail implementation with fixed array size
Now the tail have a fixed size. It actually makes everything simpler. I took
order_min = -1 and order_max = 8. This makes the tails compatible with the
previous implementation. However we might want to change this to something like
-10, 10 so that they are self-contained. This commit should also fix issue #11.
