For now use mjn:famous-views-utils to have a #FamousContext bindable to a test-local DIV. TODO move #FamousContext to meteor-famous-views
#Surface: added tests for initial value and reactive update for attribute 'size' and 'properties'. Reactive update on other attributes then size is currently not implemented in #Surface.
NEW: TestUtils - createTestDIV([width,height] creates visible DIV element with size [width x height] added to BODY.
