TransitContext is 'window' in JS
Android: correct binding of this
Add failing test for `eval("this") == transit`.
Commented out for now, but would be nice to have!
Added AndroidMock library to Android test project

Required classpath variables in Eclipse (Java > Build Path > Classpath Variables) are:

ANDROID_SDK = path to android.jar
TRANSIT_TEST_APP = path to bin folder of TransitAndroidExample (../workspace/TransitAndroidExample/bin)
add AndroidMock src
test AndroidMock.verify
refactor TransitProxy.withValue to transitProxy.proxify
TransitProxy has package-private constructor, don't use it in mock tests
test release of JavaScript functions
