Code tagging and some usefull methods for debugging and the begining of a true accumulator for time series (for any sampling rates).

Fixed the behavior of ConfigReader when throwing exceptions: it rethrows so that the error message can be turned off by the receiver of the exception (if simply not printing e.what() when catching the exception). 

The warnings in FilterAlgorithms have been turned off cast to void) since this is an algorithm that has to be re-written anyway. The documentation has been fixed (missing documentation, broken link, etc)

The new filtering and resampling framework. Filtering/Processing and Resampling have been separated from each other, the Resampling is now done with the class Meteo1DInterpolator which utilizes the static algorithms within ResamplingAlgorithms. The filtering remains a task of class MeteoFilter. The calling of the resampling and filtering as well as the data selection is now based in the facade class MeteoProcessor. MeteoProcessor::processData function calls the filtering algorithms, then passes the filtered data to the resampling algorithms and finally runs a "check only" filtering pass.

The filtering system underwent some changes in order to simplify the tasks at hand, the interface has changed.

The RateFilter is currently disfunctional, needs to be reimplemented.
