yeast 8.1.1

• Fixes:
  • Fixes #96: regardless if the model is saved with a windows or a MAC machine, the .xml file is now stored with the same scientific format.
  • Fixes #108: No CHEBI or KEGG ids are now shared by different metabolites. Also, updated the metabolites that were skipped in the previous manual curation (PR #74).
  • Remade function for defining confidence scores, which fixed 38 scores in rxnConfidenceScores (most of them from pseudoreactions).
  • loadYeastModel and saveYeastModel were improved to allow their use also when outside of the actual folder.
