This is a Spring Boot application that provides a REST API for managing play sites and kids in a playground.

The API provides the following functionality:

• Creating and managing play sites in the playground. Play sites consist of attractions such as double swings, carousel, slide, and a ball pit. Different combinations of attractions can be added to create different play sites.
• Adding kids to play sites. Each kid has a name, age, and ticket number. The API ensures that the maximum capacity of the play site is not exceeded.
• Enqueuing kids in a queue when a play site is full. The API registers queues on play sites and allows kids to wait in the queue if they accept.
• Removing kids from play sites or queues.
• Providing play site utilization at the current moment, measured in percentage.
• Providing the total visitor count during the current day on all play sites. Resets at midnight.
