> The CFFParser holds a lot of intermediate data and produces a lot of objects to do so.
The idea is to reduce the amount of such objects and data to reduce the memory footprint and
the complexity.
> - the class IndexData holds intermediate data creates byte array everytime when getBytes
is called. I'm going to replace the class with a simple list to reduce the memory footprint
and the complexity
> - remove unused members of private classes
> - create a list of strings instead of a list of byte arrays which is used to create those
strings
