* Fixed obvious bugs:
-- forgotten 'import re'
-- import user script by name from string
-- 'import converter' instead of 'import plovasp...'
* Number of iterations provided by the bash-script now has
an affect.
* Added a possibility to specify an alternative cfg-file
Now 'pytriqs' is invoked with an absolute path to the current
TRIQS installation. This ensures that the scripts will call
a compatible version of 'pytriqs'.
