Step 3 - Summarize Access
============================
This script reads modal impedances from skim files, specifies decay
rates by purpose, and calculates purpose-specific OD decay factors.
It then summarizes access scores using zonal activity data and the
calculated decay factors.

Workflow:
  - Read data
    - Travel cost skims
    - Zonal activity data
  - Specify decay rates
  - Calculate decay factors (using `emma.Decay` methods)
  - Summarize access scores (using `emma.od.summarizeAccess`)
  - Export results
