# 2014-11-16 uwe springmann:
#   reflect transciption changes in dipl: 'ꝰ':'us','ꝝ':'rum','d̉':'der','v̉':'ü'
#   additional rules for tildes instead of macrons in dipl

# 2014-11-17 vivian voigt:
# added 'oͦ':'o' to the replacement-list
# added function that checks for macrons at line seperated token

# 2016-01-12 vivian voigt:
# removed replacement of 'í' to 'i', ,'ű' to 'ü', '$' to 'us' and '€' to 'der'

#2016-03-16 laura perlitz: 
#added replacements of 'ꝰ' to 'us', 'v̉ ' to 'ü' and 'ð' to 'der'

#2016-04-06 laura perlitz:
#deleted all replacements of macrons

# 2016-05-30 vivian voigt:
# added a list of different forms of "und" and "or" (truncHelper), to differ between words that are seperated because of a linebreak and words that are seperated because of truncs

# 2016-06-02 vivian voigt:
# made the script upward compatible with python 3.x (tested with 3.4.3)
