New Structure:

  build
    |  tizen
  builder
    |  dali-builder.cpp
  demo
    |  [demo source & header files]
  examples
    |  [example-name]
    |    |  [example source files]
  packaging
    |  com.samsung.dali-demo.spec
  resources
    |  images
    |    |  [all images]
    |  models
    |    |  [all models]
    |  scripts
    |    |  [all scripts]
  shared
    |  view.h

Now, each example should be in its own subdirectory within the "examples" directory. This will get
automatically built.

README also updated.
