    Clip ToYear dates in DB.

    -ToYear for some timelines is set to 9999 to indicate ongoing event but this confilcts with minspan calculations. Therefore we need to clip ToYear values before calculating minspan.

    Keep Viewport and URL in sync.

    - Clicking on a timeline, exhibit or content item updates the URL to show the path of the clicked item.
    - When no item is clicked update the URL to show the path to the LCA.
    - Properly handle URL params such @tour and @bookmark.

    Update Merge.

    - Update Layout.mergeTimelines. Remove assertion that both the source and destination children are in the same order.
    - Update Storage.FillTimelinesFromFlatList. Remove dependancy on property SubtreeSize as it can contain inconsistent/invalid data.
    e.g Timeline '3 Large Proterozoic Craters' has no children timelines but its SubtreeSize is 7.

    Update API Search.

    Modified SearchResult to include the parent timeline containing the search result.

    Including info about the parent timeline in the search result enables the client to request the server (using API GetTimelines)  for the  missing timelines needed to render the search result on the canvas.

    Refactor progressive loading code.

    - Rename CZ.Layout.Merge  to CZ.Layout.merge (M -> m)
    - Add onfinish callback to merge()
    - Add noAnimation parameter to merge()
    - Calculate eps in calculateForceOnChildren based on timeline width instead of height
    - Bug fix: update code to better detect intersection of elements in calculateForceOnChildren
    - Change animatingElements from a hashmap to an array to better handle multiple objects with same id
    - Use a timelines isBuffered property (instead of count of child timelines) to detect if a timeline contain all its child timelines. Once isBuffered is true it can't go back to false till the page is refreshed. This garantees that the timeline will take part in the merge only once.
    - Comment out test cases 1. assert: child content cannot exceed parent and 2. assert: child content doesnot overlap
    - Move getMissingTimelines from CZ.Common.controller to CZ.Common
    - Move the check for missing data from CZ.Common.controller.gesturesSource.Subscribe and CZ.Common.controller.moveToVisible to  CZ.Common.controller.onAnimationComplete
    As a result of this change the check for missing data is performed after the animation ends instead of at the beginning of the animation.

    Remove use of goToSearchResult from clickOverBreadCrumb.

    ItтАЩs better to separate the 2 components as search might have side effects that are unnecessary for breadcrumbs.

    e.g.
    When progressive loading is enabled, clicking on a search result can request the server for the searched item if it is not available on the client.
