Code crashes when it tries to write a file in a non existing directory

Code crashes when it tries to write a file in a non existing directory. Shall we create the directory instead?

Exception in thread "main" java.io.FileNotFoundException: ../Results/true_true_Coursera_CoCoa_viterbi_chain_pairwise-1440841761677.csv (No such file or directory)

the path
solverOptions.debugInfoPath
should always be set to debug/, that directory is there.
do we have to change the parameter in some of the examples?

(if adding empty directories, need to write them explicitly in .gitignore)
