fix bug in docs
added missing comma
added placeholder files and references for the other shapes but didn't actually implement them. for example, the new files are just straight up copies of arc.js
images now added to svg
adding image is working better now, but still need to handle width/height correctly
updated demo
update docs
removed unneeded definitions for each shape
removed hard-coding of shapes with automatic definition of shape methods

gradient is kind of working
using existing markers for now. arrow and tbar are starting to work, but the positioning isn't quite correct yet
marker orientation appears to be working
added svg creation
refactored svg creation so it's more generic
move to duck typing
render the shapes instead of just preparing for rendeirng
