"""
timeseries_modeler.py

Read a two-column CSV (time, value). Read a JSON file with the same filename
appended by ".p" (e.g. data.csv.p) into a data dictionary. Create a clone of the
time-series and run a loop that steps through timestamps, calling a user-
customizable model-step function to produce a modeled series. At the end the
script computes Pearson's correlation coefficient and the variance of the
squared errors (and also MSE), using library routines.
