[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.
What's the need of this interface?  Why can't we just work with TimeInterval[]'s
