SmartyStreets JavaScript SDK Utilities

This library provides utility functions to perform additional analysis on responses from the SmartyStreets US Street API, specifically for lookups validated through the `smartystreets-javascript-sdk`. It offers functions like `isValid()`, `isInvalid()`, `isAmbiguous()`, and `isMissingSecondary()` to interpret the deliverability and clarity of address lookups based on USPS standards. The current stable version is 1.2.9. As per Smarty's disclaimer, this software is provided 'as is' and 'as a gift,' implying an infrequent or demand-driven release cadence and limited official support, differentiating it from commercially maintained libraries. It serves as an auxiliary package to enhance the core SmartyStreets JavaScript SDK functionality rather than a standalone solution.
