Flowable training project

This is a sample project to learn how to build a Spring Boot Flowable project step by step.

Tasks to be performed

Create REST endpoints to:
- Get the list of available definitions (keys and names)
- Start a new process by its key
- Get the list of active tasks (task id, process id and task name)
- Complete a specific task by task id
- Get the image representing the current state of a process by process Id
Either use a REST client (like [Postman] to interact with your API or create your own web application client interface)
