- Cleanup - move prefixing to addMethod()
 - Fix: check for method name, not method function on object.
 - Use prefixing for most tests.
 - Ensure that references in our methods to other agave-provided methods are themselves dynamically prefixed.
 - Add Array.toNodeList()
 - getParents is now ancestorNodes()
 - Readability fixes
Remove some tests that weren't effective - JSDom currently returns arrays instead of NodeLists - see https://github.com/tmpvar/jsdom/issues/561
