[API-Design] Custom major and minor time interval arrays 

Right now there is no endpoint to manipulate possible time intervals for major and minor ticks.
With this PR I introduce an API endpoint to provide custom time intervals.
To cover basic scenario I provide function, which easily can filter existed interval within some range. It might go directly to previously mentioned API, which will accept array or desired range.
I always get nervous when I see a setter that takes in an array as an argument.   Let's say that I want to modify the existing definitions instead of create a whole new definition array, how would the usage on this be?
