Support SoftwareRequirements #66
Description
We need to be able to do 'module load' and 'conda activate' before running a CommandLineTool, so that the necessary software is available.
- Study CWL SoftwareRequirements
- Make a sub-syntax for module and Conda, or see what's there already esp. for the latter
- Implement parsing the SoftwareRequirements
- Extend cwltiny to load the software
Since both conda activate and module load modify the environment, probably the best (and certainly the easiest) way to implement this is to generate a shell script and execute that.
