Changelog for wumpus-drawing-0.5.0

0.2.0 to 0.3.0: * Moved Turtle and Grids into the @Wumpus.Drawing.Extras@ name-space. Modules here are considered sketches. * Re-implemented arrowheads and connectors. * Re-implemented monadic path construction. This is now essentially \"turtle drawing\" with a path trace. * Removed chains - a simplified implementation is now provided by Wumpus-Basic. * Re-implemented and expanded Text. 0.1.0 to 0.2.0: * Added new Shapes. * Move Geometry modules to Wumpus-Basic. * Re-implemented Chains. * Re-implemented LR-Text. Added CatText. 0.1.0: * Initial release - this is a split from @Wumpus-Basic@ making the (very prototypical - read sub-alpha, unstable...) modules in the @Drawing@ hierarchy a separate package. * Simplified Chains - chains are now regular lists (though often infinite). Drawings are made with chains using new zip-like functions. * Re-worked Shapes. * Re-worked Arrow and Arrow Tip types. * Re-worked ConnectorPaths.
