We choose chrono because it's the recomended way from c++11 onwards, and is more typesafe and
acurate https://stackoverflow.com/questions/36095323/what-is-the-difference-between-chrono-and-ctime

It will get that in c++20, but that's a little too late for us :(
So for now, conversion to/from ctime objects it is....

populate_spots is used to query for all the park_spots in db and return them in a vector.
We can keep that in memory to reduce calls to the db, but increasing the memory footprint of this
program
The design desision to use vector<T> instead of <T> is for the following
reasons:
1. some of these can potentially return more than one object. For example, 2
customers who have the same name.
2. I have no clue how many of you have done error handling in c++
(try/catch/finally).
Ya boi is nice and doesn't want to bombard you with more new concepts than needed.
so now you'd do
vector<Customer> test = query_customer_with_name("Testman");
if (!test.size()) {print no customers found, do stuff}
else if (test.size() > 1) { do stuff to get the right one if you only need one
}

try {
customer test = query_customer_with_name("Testman");
}
catch(someException.probablycalled_not_found) {do_Stuff};
catch(...) {
do stuff
}
finally{

furhter.
