enum classes make it easy to represent categories.
So you can use something like Vehicle_type::twowheeler instead of 2 in code, so you know it's that.
but under the hood, it's still an int.
This is so you don't have to polute the global namespace with unnecesary variables.
enum classes do not permit implicit conversion between int and the enum class, and are in the
Enumclass:: scope in contrast to plain enums. https://en.cppreference.com/w/cpp/language/enum

Customer constructors do the same stuff as all the other constructors.
clock_in and out create and modify park_time objects and store them to

It might have some performance benefits to keeping it, though.
TODO: test or fix this.
save, update, delete and auto increment are the same as in park_time but for customers.
