Title: 2013 08 25 process simplest expression

Next TODOs:

- Pass the whole node of source code to metamorphoser_module

e.g.
```ruby
# Before
Metamorphoser_module._metamorphose_piece( (hoge( ... )), "hoge", 1, 2 )
# After
Metamorphoser_module._metamorphose_piece( (hoge( ... )), "hoge(...)", 1, 2 )
```
- Support other cases:
- operators
- block
- other control structures (such as if, begin, etc.)
- Of course more!
- Restructure internal classes according to the future problems.
- Change Metamorphoser module into class so that it can make many instances to wrap source code more flexibly.
