The main changes are:
* The Liftover/phase/Imputation pipeline saves temporary file in a TMP_<random_id> 
* This means that on the worksheet now we have to define an extra variable with name: randomUUID . This should be just a random string.
* When the analysis finishes, the data are COPIED (instead of moved) to the output directory
* I created new parameters files: parameters_unique.csv . These files contain only the parameters that are used in the specific workflow (for exaple in phasing). There is also another parameters file: compute5/Imputation_impute2/constants.csv that contains all the constants. So (At least) two parameters files should be declared: (1) the parameters_unique.csv and (2) constants.csv
    * The reason for this is that molgenis-compute seemed to have some problems with variables that were defined in more than one parameters files. So in order to combine more than one workflows (for example phase + imputation) we have to make sure that one variable does not exist in the parameters.csv file of both workflows. 
* New version of genotype harmonizer
