Definition of the interface for the hardwareabstraction for reading from files
hardware abstraction layer implementation for POSIX
Refactoring of the structure into an internal and external part. Also all malloc code was move from the sequence parsing code
Included a mapping between internal file descriptors and the one povided by the hwal-API

Read first the head and the following complete frame
better error handling
The abstraction layer for the file handling works completely
Removed some comments needed for the development
