[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 would like to keep formatter idea even if it is additional ~10 chars. Formatter is sth that gets's an object and return string. While keeping a string, then we will need to explain what is this, but users are already familiar with formatters.
