feature: compile source code transformation to binary code transformation

For the programmer, it is much easier to write a transformation at the source code level, because she is familiar with the language constructs. However, in many cases, it is better to be able to apply the transformations at the binary level (eg one could apply the transformation on binary code for which we don't have the source code).
For doing this, there are different options:

1. compiling a source code transformation in Spoon to a binary code transformation in ASM/Javassist
2. applying transformation after decompilation.

The first option is the most fun: write a transformation at the source code level, and then compile the source-level transformation to a binary-level transformation (in our case writing a Spoon transformation and compile it to an ASM/Javassist transformation)
