Advanced Custom Fields: Polyline Generator

This plugin extends the Advanced Custom Fields system by adding a field type that requests and stores directions data from the Google Maps API. It is designed for developers building websites that need to display custom routes or directions on embedded maps without manually handling API calls and data caching for each page load.

• Polyline Generator Field: Adds a new field type where you input start and end coordinates, along with optional waypoints, and generate the route data directly within the admin interface.
• Automatic Data Caching: Sends a request to the Google Maps Directions API and stores the returned data (like encoded polylines or steps) within the field, preventing repeated API calls on every page view.
• Front-End Integration: The cached route data is stored and can be easily passed to the front-end for use with JavaScript mapping libraries to display the generated directions.
• Coordinate-Based Workflow: You provide geographic coordinates, and the plugin handles the API communication, simplifying the process of adding complex route data to posts or custom post types.
