The timeline is one of the most important components within the FlexGantt 
framework. It contains the dateline and the eventline. The dateline is 
responsible for displaying dates (Mo. August 5th, Tu. August 6th, ...) while the
eventline displays global events and activities. 'Global' means, that they can
not be attributed to a specific row within the Gantt chart but that they are 
relevant for all rows (e.g. company holidays, national holidays, company-wide
milestones...).
