0.0.4

Major changes

• Rename viewer class to VLWholeSlideMicroscopyViewer
• Refactor class constructor: metadata needs to be passed to the constructor. This allows creation of the Openlayers Map upon construction of a viewer instance, which then allows the render() method to be called on the instance without having to resolve the promise for retrieving the metadata
• Add vector layer to enable drawing (the drawing functionality is not yet exposed)

Bug fixes

• Reassembling of concatenation parts
• Calculation of frame coordinates when dimension organization is TILED_FULL, i.e. positions of individual frames are not specified
