U.S. State Mapper 
This library maps an input string into a U.S. State, a U.S. territory, or the District of Columbia.
Current Capabilities
Takes as inputs:
- State names (including territories and federal districts)
- USPS two-letter abbreviations
- ISO 2+2-letter codes from ISO 3166-2 (e.g., US-PA)
- ANSI two-digit codes (e.g., 04 for Arizona)
Returns:
- Official U.S. State name
TODO
There are several features I will be building out over time
- Ability to convert an input string into the USPS recognized two-letter state abbreviation.
- Accept US Coast Guard two-letter abbreviations as input.
- Accept Old GPO state abbreviations as input
- Accept AP stylebook abbreviations as input
- Accept other recognized state abbreviations as inputs.
- Fuzzy match strings for state names.
Usage
var stateMapper = new StateMapper();
var result = stateMapper.ToState("PA"); // result is "Pennsylvania"
result = stateMapper.ToState("Newyork"); // result is "New York"
result = stateMapper.ToState(" Utah "); // result is "Utah"
result = stateMapper.ToState("US-ME"); // result is "Maine"
result = stateMapper.ToState("04"); // result is "Arizona"
