ECM Simple Degradation
=======================

This example demonstrates the simple degradation model of the Equivalent
Circuit Model (ECM), where capacity and resistance evolve as functions of
*capacity throughput* -- the running integral of absolute current,
``int |I| dt`` in A.h.

Key concepts demonstrated:

- Turning degradation on with the ``"capacity"`` / ``"resistance scale"`` options
- Using the ready-made ``linear_capacity_loss`` / ``linear_resistance_increase``
  helpers for the common "X% per full equivalent cycle" case
- Writing a custom degradation function of any of the degradation inputs
  (here, calendar time)
- Reading the degradation outputs from the solution
