Loading multiple data files of the same format type
===================================================

Processing data found across multiple files and performing analysis on them

.. GENERATED FROM PYTHON SOURCE LINES 8-10

Skutils loaders can only open one file per "loader object", meaning that you
need to "instantiate" a new loader for every file you open, here's an example

.. GENERATED FROM PYTHON SOURCE LINES 10-18

    import skutils
    import matplotlib.pyplot as plt
    import numpy as np

    # There will be a planned capture of real data for 
    DATA_FILES = []

Iterate over every file

        loader = skutils.EventCSVLoader(file)
