Corrected dataset names that didn't match with the other versions

Only standard star cubes can be read
Uses new type for collection of stars
ToDo: sorted cube, mpi cube, mpi sorted cube

Type with allocatable arrays for particle properties, logical to
show which properties are used, and size (nb of particles)
Extension for stars and dm particles
Subroutine to allocate the arrays and set the size for the 3 types

Function to handle allocate errors: abort run
ToDo: close every file before abort

Conversion from integer4 to char(len=5): useful for process rank

Group for do_timings has been corrected

New file with type_particles

amr2cell can compile
has to be tested

Tool to write cubes with hydro and grav data
(name will change)

Many undocumented changes
haloanalyzer development is suspended until cubes with hydro and grav are available

Add a mod and a obj directories for modules and object files
Compile modules and objects in these directories

Add mod and obj directory for build

Change some constant or type names
Adapt Makefile

Add a subroutine to read halo_dm_data
Correct some bugs in H5read_halo_hfprop

Debug target different from release target

Closes https://gitlab.obspm.fr/roy/pFoF_dev/issues/1
If particle type is star then constant_mass = 0
If particle type is dark matter then constant_mass=1 if do_skip_mass=true and constant_mass=-1 if do_skip_mass=false

Fix #5
Compute global_npart for DM particles in Select_dm_particles
Remove global_npart computation from modio.f90
Write correct global_npart in modwritehalo.f90 and modwritedmcube.f90
Add global_npart to the calling arguments of the subroutines that write halo hdf5 files in modfofpara.f90

The 4 different cube are implemented
A first test has been passed
Implements #8 issue

Write dataset in parallel only if the whole dataset in not empty
i.e. if the global size of the array is not 0

write a message for star cube output

Downcase + some small changes in names of variables

Warning: the fin=deb line is a potential source of problems

New file in object list: modwritestarcube.f90

Add particle type as optional input parameter to Write_meta_common
If particle type is not present, default value is dark matter.

global_npart can now be != nres**3

Remove some useless variables declaration and some useless debug info

There was a compilation warning otherwise

Not tested + one subroutine not adapted from dmcube.

Add call to Selectwritestarcube and Writestarcube

Communication to compute global_nstar
Remove a useless comment
