trying to get a custom text datastructure working as a string
text now properly subclasses from str
single testmodule can now be specified in runtest.py
some test architecture rewrite; tests still failing
intermediate commit IMPORTANT: userinterface api has changed
Merge remote-tracking branch 'origin/custom-text-datastructure' into gfate-intergration
IMPORTANT: textdatastructure still broken
