/**
* The BBCAnalyser implements the HeaderAnalyser interface and includes the analysis 
* functionality.
*
* The BBCAnalyser includes two kinds of analysis. Firstly, some frequently used 
* properties of declarations are calculated and saved in XML document for usage
* in further analysis. These are implemented in classes implementing the 
* PreAnalysis interface.
*
* Secondly, the declarations are analyzed by classes that implement the
* NodeAnalysis interface. The idea is to have the top level NodeAnalysis to analyze
* all global declarations and delegate the complex declarations to other 
* NodeAnalysis classes for further analysis. This enables the problem partitioning
* in solvable units and keeps the analysis algorithms maintainable.
