class ProcessManager(object):
    r"""
    valf internal class to provide essential processing for observers

    - initialize

        - start logger
        - initialize data_manager
        - search classes based on class BaseComponentInterface

    - load configuration

        - import declared observer modules
        - set data ports

    - run validation

        - call all methods of all observers sequentially
        - use bpl_reader or similar to run through all recordings

    This class also is responsible to read out configuration and interpretation from config file.

    general used ports on bus ``Global``:

        - set "ConfigFileVersions"
            dict with file name as key and version as value for each loaded config file
        - read "FileCount"
            to show progress bar
        - read "IsFinished"
            to continue with next state when all sections of a recording are validated (set by `SignalExtractor`)

    Also setting ports as defined in ``InputData``  for the named bus.
