 Changes in v2.2.0 compared to v2.1.1
-----------------------------------------------
dprice (63):
      BUG FIX/regression with int*8 and int*1 definitions in sphNG data read
      less verbose warning if no gas particles (warns for first file only)
      BUG FIX with sink particle read in phantom small dumps
      catches problems with vector labelling in data reads
      updated jules data read to handle his latest format
      added CMRmap colour scheme: A colormap for effective black and white rendering of colour scale images
      implemented splash to grid in 2D
      added splash to gadget option to convert files to basic gadget code format
      build dependency fixed (thanks to Shazrene Mohamed)
      confusing/obsolete linkerror diagnostic stuff removed from Makefile
      kernel swapping implemented (using SPLASH_KERNEL environment variable): applies to ALL interpolation routines
      openMP bugs fixed with kernel swapping stuff
      bug fix with memory allocation in splash to grid if npixels exceeds int4 limit
      bug fix with openMP in splash to grid + kernel swapping
      kernel swapping implemented as menu option in r) menu; also choice saved to splash.defaults, overrides SPLASH_KERNEL setting
      new kernel module added
      interactive mode prints help screen automatically on first call
      implemented floating/inset and customisable colour bar options
      vastly improved the menu interface for adding/editing shapes/annotation
      better error handling with ctrl-t in interactive mode if hit array limits for text shapes
      added new prompt_list module for list-based menus; shapes menu now implemented using this
      animation sequences menu uses new list prompting module: much less confusing
      unused variable warning fixed
      compiler warnings fixed
      updated version info
      uses print_shapeinfo to pretty-print shapes during plotting
      .anim files no longer used, animation sequence options now just saved to splash.defaults; much less confusing
      better question about buffered data
      added kernel function for M5 quartic squashed to 2h
      line break before interactive help (looks nicer)
      get_columns no longer prints number of columns (less verbosity)
      ascii data read prints column assignment info only for first file read
      consistent definition of lastplot done in page_setup; printing of plot limits less verbose for multiple steps-per-page
      Makefile uses FC, FFLAGS instead of F90C, F90FLAGS; also version number checked for gfortran compatibility
      compile error in gfortran 4.7 fixed
      compiler warning fixed
      footnote fixed
      minor bug with string indexing fixed
      bug fix with weird limit-changing behaviour with a) on surface density/toomre Q plots
      BUG FIX with splash to ascii if coordinate transform set (now works)
      integrated kernel table setup does not print anything
      changecoords and changeveccoords routines moved to geomutils module
      bug fix with velocities in cylindrical coords + calc quantities if radius is relative to tracked particle
      splash to ascii uses origin settings if cyl/sph coords are used
      commented out cruft removed
      bug fix with allowed range of columns in render prompts if extra quantities present
      much faster r-z and non-cartesian rendering
      bug fix with gadget HDF5 read with dark matter only + no gas
      automatically turns on plotting of dark matter particles if no gas particles read; dependencies rejigged to enable this (set_coordlabels moved; also does not reread coord labels when resetting coord system)
      minor changes to comments
      bug fix: GSPLASH_DARKMATTER_HSOFT now works with gadget hdf5 read
      bug fix with axes colours in residual error plots
      titles continue on next page if ntitles > nacross*ndown
      added gresho vortex exact solution
      bug fix with axes being redrawn with multiple steps per page (looks odd in eps)
      maxshapes increased to 32
      rendering in non-cartesian coords uses normalised interpolation if 3rd dimension is not a length
      docs updated for 2.2.0
      v2.2.0
