The class mtkExpWorkflow
is used to manage the processes involved in a sensitivity analysis.
We can construct a workflow in two ways: either from pre-defined factors and processes or from a XML file.

######## Example 2: Construct a workflow from a XML file
##############
# Create a workflow from XML file
## Nota: If your XML file is a local file
## for example /var/tmp/X.xml", you should
## create the workflow as follows:
## workflow <- mtkExpWorkflow(
## xmlFilePath="/var/tmp/X.xml"
## )
xmlFile <- "WWDM_morris.xml"
## If WWDM_morris.xml is a local file, the next line is not necessary.
xmlFilePath <- paste(path.package("mtk", quiet = TRUE),
"/extdata/",xmlFile,sep = "")
workflow <- mtkExpWorkflow(xmlFilePath=xmlFilePath)
# Run the workflow and report the results
run(workflow)
summary(workflow)
