fcc53f6edf Massive code cleanup 
New conservative transfer function scheme.
New random number generator that preserves coarse Fourier modes instead of applying Hoffman-Ribak
Some minor bugs fixed.

275753ede2 Many minor changes 
* Moved hybrid poisson solver from convolution_kernel.cc to poisson.cc
* Fine-tuned deconvolution schemes for various running modes
* Added lots of doxygen documentation

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!

785601d4ae Speeded up transfer function calculation significantly. 
Added an approximate log10 algorithm.
Use spherical symmetry of problem to avoid computing duplicate values.

fbebfabdfb Fixed a minus in 2LPT. Fixed an issue with a deconvolution filter. 
Code needs cleanup! Added (undocumented) k-space 2LPT.

002763346f major mod: added subgrid deconvolution for DM 
* The DM transfer function is now deconvolved with the cell assignment
  function in order to restore power near the Nyquist wavenumber.
* Added an option to change the random number sample cube size
  [random]/cubesize. This should be set >128 to generate un-
  correlated numbers. True fix pending.
* Removed some unused code
* Increased Buffer size for Gadget-2 output plug-in
