Added an SBT build file and moved the source code to use the standard SBT
directory layout. (Essentially each file was moved from the
src/com/ucombinator/dalvik/* to src/main/scala/com/ucombinator/dalvik/*.)
   build.sbt (new), src/main/scala/com/ucombinator/dalvik
   (moved from: src/com/ucombinator/dalvik):
   AST/ClassDef.scala, AST/DexReader.scala, AST/FieldDef.scala,
   AST/Instruction.scala, AST/MethodDef.scala,
   analysis/AbstractCounterInt.scala, analysis/Address.scala,
   analysis/FramePointer.scala, analysis/State.scala, android/README
Added basic APK file reader.  Currently, it is just used to extract the dex
file and read it, but eventually I'd like to have it make the resource files
available.
  under: src/main/scala/com/ucombinator/dalvik:
    AST/DexReader.scala, android/ApkReader.scala (new)
Created an initial analyzer application that can be handed an APK file and can dump the contents of the file after it has been read by the DexReader.

Removed some debugging printing helpers.
   src/main/scala/com/ucombinator/dalvik/AST/DexReader.scala

Added an analyzer with the ability to dump class definitions,
procedures, and the associated byte code.
