* Notes:
* - Doesn't really make sense to put this on a method with parameters.
* - Creates an obscure non-enumerable property on the instance to store the memoized value.
* - Could use a WeakMap, but this way has support in old environments.

Ionic/Cordova update platform config
#!/usr/bin/env node
/** This hook updates platform configuration files based on preferences and config-file data defined in config.xml.
Currently only the AndroidManifest.xml and IOS *-Info.plist file are supported.
See http://stackoverflow.com/questions/28198983/ionic-cordova-add-intent-filter-using-config-xml
Preferences:
1. Preferences defined outside of the platform element will apply to all platforms
2. Preferences defined inside a platform element will apply only to the specified platform

Fast SQLAlchemy counting (avoid query.count() subquery)
def get_count(q):
count_q = q.statement.with_only_columns([func.count()]).order_by(None)
count = q.session.execute(count_q).scalar()
return count
q = session.query(TestModel).filter(...).order_by(...)
# Slow: SELECT COUNT(*) FROM (SELECT ... FROM TestModel WHERE ...) ...
print q.count()
