Initial implementation of the AI-SPRINT design tool.

Currently implemented functionalities:

• Creation of new AI-SPRINT applications from template (based on cookiecutter)
• AI-SPRINT annotations (security annotations must be added)
• Parsing of AI-SPRINT annotations (security annotations must be added)
• Creation of AI-SPRINT designs (base + partitions
• Generation of configuration files for each design given the provided annotations:
  • Currently only 'exec_time'-derived constraints for monitoring tool
• Some error checking:
  • DAG format
  • Annotations syntax. Implemented for:
    • component_name
    • exec_time
    • expected_throughput
    • partitionable_model
