[Suggestion] Extension of the JSON format #18

Currently, the one-to-many and many-to-one relationship are implemented as demonstrated by the energy volume curve example. There are still a couple of things missing:

• dynamically modified workflows - for example a while-loop which adds steps until the condition is fulfilled.
• computational resources - to submit jobs to high performance computing clusters
• conda environment - dependencies of the workflow can vary from one node to another
• nested workflow structures - while the workflow frameworks have names for this functionality, most provide the option to nest workflow structures
