Lunar workflows
Workflows are the core objects of Lunar and they represent the task to be performed using one or more Lunar Components.
A workflow can be interpreted as a directed acyclic graph of components connected by dependencies (edges).
Workflow run
For every workflow run, a new process is created, and it also dynamically creates an isolated Python environment with all resources and libraries needed for the execution of every workflow component.
