Code review comment for lp:~pkunal-parmar/ubuntu-calendar-app/TimeLineView

138 + property bool expanded: false
139 + property bool expanding: false
140 + property bool compressing: false

As a side note, the above code (and all associated animations) could be largely simplified by using QML states (see http://qt-project.org/doc/qt-5.0/qtquick/qtquick-statesanimations-states.html).
This can be addressed in a separate branch though.
