Discontinuous events with multiple dates: native method with date fields and matrix

  {#
    Tackling discontinuous events without duplication

    - Each event has a 'startDate' and an 'endDate' (those are just a date interval, the first date corresponds the the first occurrence of the event and the mast one corresponds to the last occurence of the events). This matching is done manually but we could also use the preparse plugin.
    - Each event has got a matrix field 'timetable' with just a block 'mxBlockDate' and date field 'mxDate' for each occurence of the event

    1. When the users query for a day or date range when the event does not occur, we shouldn't display antyting
    2. For each day during which the event occurs, we want to display the event's details
