Better header

[GoogleCodeExporter]

1. The header should contain some useful information and statistics:
- number of objects
- number of classes
- date and time of serialization
- author
- image data (platform, version, image file name)
- (class names)
- (number of objects of each class)
- (amount of time it took to serialize)
- (purpose, e.g. serialized debugger)

2. To achieve the above the header needs to be serialized after analysis, i.e. 
in the materialization object, not the materializer as is currently the case
