• added LINE visvars: texture, form, rotation -- uses polygons of BUFFERed lines (expects a file named %DATA_URL%_buffer).
• added POINT visvars: colour, form, texture, orientation, value and size
  • for orientation used a workaround from #jwoLondon, in expectation of angle encoding slated for VL 4.1.
• refactored templating system to use semantic naming: %TEMPLATE_ITEM% instead of simple 'TEMPLATE' search & replace - total rewrite of fillTemplate(items) and createMap(guiState)
• renamed function getParameterByName(name) to more appropriate getURLParameterByName(name)
• some small changes in CSS styling (eg. data browser)

• cleaning up versioning and updated OER for 2019 courses

• added choice between AREA and LINE data
• implemented quantitative strokeWidth encoding => in LINE implemented visvars color, value, size - still missing texture, form, rotation

• added an OER (Online Educational Resource) explaining the principles of the Cartographic Grammar. Uses getURLParameterByName('from_oer') to test if we need to ask for OER.

• added fillDataViewer(attrib) to preview values for selected attribs
• using point-in-area symbols for 'form' visvar
• added hatched fills for orientation visvar
• moved legend to right side

• added data/attribute/title chooser to gui and logic
• implemented vega-lite json templating
• made compatible for Chrome/FireFox/Safari/Edge
• added SVG patterns to use in textured fills

• changed to using gui.state codestrings
• added hasOwnProperty() check in for boxes in iterations

• initial test version
