### OVERVIEW ###
Takes a US mailing address (including street, city, state, and zip) and looks up the corresponding Congressional District via AJAX. Geolocation (lat/long lookup) is first completed using the Google Maps API and then passed onto the Sunlight Labs API to obtain the congrssional district. The basic script returns a value in the form of "State Abbreviation-District #", such as MI-9 or CA-30.

The "Look Up" is triggered when a 5 digit zip code has been entered; it will re-fire if the zip code is changed. Note that the Google Maps API determines the ultimate Geo code and will resolve conflicts as it deems fit (e.g., when the street address does not agree with the zip code).

### REQUIREMENTS ###
-PHP
-JQuery
-Google Apps API Key
-Sunlight Labs API Key

### USAGE ###
-Enter your Google Apps API Key on line 46 of index.html
-Enter your Sunlight Labs API Key on line 9 of inc/sunlight-php/districtLookupByGeo.php

The project is configured to work with the supplied form. Revisions to input IDs in index.html, require similar changes to the following portion of js/lookup.js:

	// Add Congressional District - Main Pledge Form
	$("#zip").bind('keyup',function()
	{
		// when the entered zip code reaches 5 characters 
		if(valueLength(this) > 4)
		{
			codeAddress('address1','city','state','zip','#district');
		}
	});

Ensure that this function is bound to the zip code field using an approiate selector. Additionally, the "codeAddress" function takes 5 arguments: 

(1) the ID of the street address input; 
(2) the ID of the city input;
(3) the ID of the state input;
(4) the ID of the ZIP code input;
(5) the selector for the target input (i.e., the destination of the returned congressional district)

### CREDITS ###
The project includes a modified version of code of the Sunlight Labs API PHP Library orginally developed by Aaron Brazell (see http://emmense.com/sunlight-labs-php-library/). The modified version of the PHP Libaray fixes an issue described at http://code.google.com/p/sunlight-api/issues/detail?id=1#c2 where the PHP Library failed upon supplying a ZIP code beginning with a zero. The fix does not actually impact this particluar implementation of the PHP Library, since the fix applies to a part of the library not used by this Git project. However, it seemed appropriate to distribute the modified version in the event the project is forked and modified. All other code in the PHP library (inc/sunlight-php/class.sunlightlabs.mod.php) reflects the original Library code.
