Bug

No dependency between Interview -> Press meeting
Dependency for Press meeting -> Script deadline is partially below Audition

##Sample code

const scheduler = new Scheduler({
    adopt : 'container',

    startDate : new Date(2018, 4, 6),
    endDate   : new Date(2018, 4, 13),

    features : {
        dependencies : true
    },

    columns : [
        { field : 'name', text : 'Name', width : 100 }
    ],

    resources : [
        { id : 1, name : 'Bernard' },
        { id : 2, name : 'Bianca' }
    ],

    events : [
        { id : 1, resourceId : 1, name : 'Interview', startDate : '2018-05-06', endDate : '2018-05-08' },
        { id : 2, resourceId : 1, name : 'Press meeting', startDate : '2018-05-08', endDate : '2018-05-09' },
        { id : 3, resourceId : 2, name : 'Audition', startDate : '2018-05-07', endDate : '2018-05-10' },
        { id : 4, resourceId : 2, name : 'Script deadline', startDate : '2018-05-10', endDate : '2018-05-10' }
    ],

    dependencies : [
        { id : 1, from : 1, to : 2 },
        { id : 2, from : 2, to : 4 }
    ]
});

Result

BTW

Same code with time gaps between events

        { id : 1, resourceId : 1, name : 'Interview', startDate : '2018-05-06', endDate : '2018-05-08' },
        { id : 2, resourceId : 1, name : 'Press meeting', startDate : '2018-05-09', endDate : '2018-05-10' },
        { id : 3, resourceId : 2, name : 'Audition', startDate : '2018-05-07', endDate : '2018-05-10' },
        { id : 4, resourceId : 2, name : 'Script deadline', startDate : '2018-05-11', endDate : '2018-05-11' }
