Reduce copying of data structures

[GoogleCodeExporter]

The formatter contains several data structure bridges where data is packaged in 
objects, then unpacked, then repacked using the same class (or a similar 
class). This causes an unnecessary load on the system, clouds the data flow and 
makes the code harder to maintain.
