When you run this code, it will:
1. Evaluate all possible paths from 1 to 8 taco spots in all possible orders
2. Calculate the metrics for each path:
    * Total tastiness
    * Total distance traveled (from start through all visited spots)
    * Ratio of tastiness per distance
3. Find the optimal path that maximizes the ratio
4. Display detailed results including:
    * The optimal sequence of spots to visit
    * Total tastiness achieved
    * Total distance traveled
    * The optimized ratio value
    * Step-by-step route details
The code uses a brute-force approach since the problem size is manageable (about 2 million permutations total for paths of length 1-8). It will typically run in a few seconds to a minute depending on your computer's speed.
Key features:
* Clear, readable code with comments
* Progress reporting during computation
* Detailed output showing the reasoning
* Step-by-step route visualization
* Performance metrics (paths evaluated, computation time)
This solution will definitively find the globally optimal path for the taco crawl challenge according to the specified criteria.
