  Update README.md
  result layout standardised, iterator size more elegant
  updated syntac in Test_hadrons_spectrum
  chroma-regression test now prints difference correctly
  baryon input strings are now pairs of pairs of gammas - still ugly!!
  second update to pull request
  Changing back interface for Gamma3pt
  Removing old debug code
  Changes to A2Autils
  suggested changes for 1st pull request implemented
  changed input parameters for easier use
  Should compile everywhere now
  changed baryon interface
  added author information
  ready for pull request
