Ian Jauslin 3f0510629e Update to v1.5.
The update to version 1.5 is rather substantial, and introduces some minor
  backward-incompatibilities:
    * The header "#!symbols" has been replaced by "#!virtual_fields"
    * Multiplying polynomials using the '*' symbol is no longer supported (or,
      rather, the symbolic capabilities of meankondo were enhanced, and the
      syntax has been changed).
    * 'meantools exp' has been removed (its functionality is now handled by
      other means)
    * 'meantoolds derive' has been replaced by 'meantools differentiate'

  * The symbolic capabilities were enhanced: polynomials can now be
    multiplied, added, exponentiated, and their logarithms can be taken
    directly in the configuration file.

  * The flow equation can now be processed after being computed using the
    various "#!postprocess_*" entries.

  * Deprecated kondo_preprocess.

  * Compute the mean using an LU decomposition if possible.

  * More detailed checks for syntax errors in configuration file.

  * Check that different '#!group' entries are indeed uncorrelated.

  * New flags in meankondo: '-p' and '-A'.

  * New tool: meantools expand.

  * Improve conversion to LaTeX using meantools-convert

  * Assign terms randomly to different threads.

  * Created vim files to implement syntax highlighting for configuration
    files.

  * Multiple bug fixes
