2 commits - java code gen + cleanup / removal of iostream

1. Some work related to java code gen
2. got rid of iostream and added keep runtime alive in emscripten

had to switch back to js code gen, because some people we contacted
earlier came back now and asked for demos

 work being done in cleanup includes
 1. adding capture questions inside a for loop
 2. add geocode questions inside a for loop

 Earlier code gen was not handling this case, as I had programmed things
 in a hurry.
