Support Non-File Outputs #1135
Description
In CWL, it's possible to specify an output as a number or string by pulling it from a file. This would make it a lot easier to query for certain tasks after a workflow executes. This is an example of how it works with CWL (they use javascript evaluation): https://www.biostars.org/p/347023/
Instead, we can just detect whether the user wants to store it as a number or string or not and then try to do that storage for them (via loadContents + type)
