+When `PDAF_init` is called, the filter algorithm is chosen by its ID number. Internally to PDAF, each filter is identified by a string that is defined in `PDAF_init_filters`. The interface routines have a very simple structure. In general, they select the filter-specific routine based on the string identifying the filters. When a filter algorithm is added a line for the corresponding filter-specific routine has to be inserted to each of the interface routines.
