Description

As it stands, it is not clear what a sigpro.SigPro object actually is from the name alone. Currently, the approach to constructing and running a pipeline is to instantiate a sigpro.SigPro object:

mypipeline = sigpro.SigPro(transformations, aggregations, keep_columns = True)

Following this, we can run the pipeline on sample data using the process_signal instance method, which under the hood calls the _apply_pipeline method:

processed_data, feature_columns = pipeline.process_signal(dataframe, '1h', time_index = 'timestamp')

However, the sigpro.SigPro constructor itself calls the _build_pipeline method to actually build the pipeline. A more intuitive interface would look like:

mypipeline = sigpro.create_pipeline(transformations, aggregations, keep_columns = True)

This new create_pipeline method should still return a SigPro pipeline (potentially not a sigpro.SigPro object), and should preserve the process_signal interface.
