  Project Planning and Task Management Function Block
  
  This function block implements a basic project planning and task management system in TwinCAT 3 Structured Text. It allows for the creation and tracking of tasks within a project, calculation of project progress, and integration with a collaboration system.
  
  Key features:
  1. Task storage using an array of structured task data
  2. Project progress calculation
  3. Integration with separate task management and collaboration function blocks
  
  Potential TwinCAT 3 features to enhance this implementation:
  1. Use of TwinCAT HMI for creating a user interface for project management
  2. Implementation of TwinCAT Database Server for persistent storage of project and task data
  3. Utilization of TwinCAT OPC UA for secure data exchange with other systems or remote monitoring
