GetFilePath this is only populated _after_ readInConfig().

InitConfig reads in config file and ENV variables if set.

FunctionAverage computes the average value of all referenced curves using the arithmetic mean.

FunctionDelta computes the difference between the biggest and the smallest value of all referenced curves.

FunctionDifference computes the difference of all referenced curves.

FunctionMaximum computes the biggest value of all referenced curves.

FunctionMinimum computes the smallest value of all referenced curves.

FunctionSum computes the sum of all referenced curves.
