3ad0ac6a10 Fixed a memory leak. 
Slightly better memory conservation.
Fixed a bug introduced in the previous revision that led to code termination.

27fe21e3d4 Migrated several implementations to .cc files. 
Some minor bugfixes.
No longer use Akima splines, use cubic splines in tabulated transfer functions
Added more ocnstraint infrastructure.

485d6f2a4e Gadget2 plugin: Important Bugfix. Bug introduced two versions ago that caused the first particle 
to have zero mass, which caused Gadget to choose a zero time step.

f3364e9877 * Added support for velocity potentials for baryons and CDM 
* Added new transfer function type 'music' which reads in a file with
  density and velocity transfer functions for baryons and CDM.
* Powerspectrum evolution in two-fluid sim appears to scale as
  predicted now at the per cent level
* Tool to compute velocity transfer functions is not included as of
  now. Let's see..
* Velocity potentials are not yet supported with 2LPT.

61caef1575 2LPT now reuses velocity data to compute displacements in pure DM case (instead of recomputing everything). 
Random number generator now creates 'dummy seeds' if seeds are not specified

dec2181626 Some more 64bit related fixes. 
Fixed a bug in the Gadget-2 output that was left from an unfinished modification.

c98e030c7c Updated MUSIC internal array access to 64bit compatibility. 
Added support for FFTW3 (can be switched on in the Makefile), needed for
64bit compatible FFTs.

332362ce0c Added buffered writing for Gadget-2 I/O plugin that prevents overflows of STL ofstream operations. 
Buffer block size can be set by [output]/gadget_blksize, default is 2**20=1048576 so that the
buffer contains 8*2**20 bytes for doubles = 8MB for one write/read operation

c09f2adbe4 Random numbers are now only generated once. Can choose between memory caching and disk caching of random numbers 
in conf file (option '[random]/disk_cache={yes|no}').

7eeba48408 Changed T(r=0) determination to 3D adaptive Gauss-Kronrod integration rather than spherical approximation. 
Seems very accurate in very first tests.

ad709d7400 Various minor fixes. 
* Fixed a bug in the coarse grid density correction that lead to a shift in the correction in some rare cases
* Fixed a bug in restricting fine grid noise when the double size fine grid (for FFT) is actually larger than the domain.
* Added new log file routines that use printf syntax
* Added log file output to most parts of the code
* Removed the stats file output, it is now appended to the log file

af02e4ef4e Added new fine-grid hybrid poisson solver. This can be turned on with '[poisson]/fft_fine=yes'. Needs more testing though. 
Also added a cut-off for baryons when using CAMB tabulated transfer functions to reduce ringing.

b7083b0217 Important: Fixed a missing logarithm 
Last changeset used a wrong transfer function as a logarithm
had been removed and not put back. This is fixed now!
