We need to iterate over irregular intervals, like months or years.
The idea is to put this logic into a data structure, the units.
Just like the 0-th second is 1970-01-01 00:00:00, the 0th month
is 1970-01, or the 0-th century is the 20th century.
A month unit, for example, has the following properties:
- seconds: average number of seconds (used to compute width at zoom)
- date: returns the start date of the index-th month
- name: returns a string representation of the index-th month
- value: returns the month index for a given date
