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!

5d3b66e96a Added new interpolation scheme for long-range component. 
The LR part is now interpolated directly to fine grids from coarse grids not
involving intermediate grids. This improves accuracy for >=2 levels.

the mean velocity in the finest refinement grid.

b3622955e8 Added a new averaged transfer function for coarse grids. This beats down errors there and 
improves the solution.

Also fixed another bug related to the previous grid placement correction with align_top,
size corrected grids have to be enforced to have an even offset.
