EXAMPLES: Mostly cosmetic changes so the examples match each other better

• InternationalAutocompleteExample: Added try/catch block
• InternationalExample: Added try/catch block, separated printing of results into separate function (public, maybe should be made private)
• USAutocompleteProExample: Added try/catch block, separated printing of results into separate functions (these ones are private)
• USExtractExample: Added try/catch block, separated printing of results into separate function (public, maybe should be made private)
• USReverseGeoExample: Added try/catch block, separated printing of results into separate function (public, maybe should be made private)
• USStreetLookupsWithMatchStrategyExamples: Removed unnecessary try/catch block

NOTE: These have a different naming convention (Us vs the above US, which ones should it be?)

• UsStreetMultipleAddressesExample: Removed unnecessary try/catch block
• UsStreetSingleAddressExample: Removed unnecessary try/catch block
• UsZIPCodeMultipleLookupsExample: Removed unnecessary try/catch block
• UsZIPCodeSingleLookupExample: Removed unnecessary try/catch block

EXCEPTIONS: Added three new exceptions.

• Added RequestTimeoutException (408)
• Added BadGatewayException (502)
• Added MustRetryException: Specifically for testing, we may be able to get rid of this with some additional work
• Added a parent constructor to SmartyException so users can use getCode on the SmartyExceptions (GitHub issue #20 https://github.com/smartystreets/smartystreets-php-sdk/issues/20)

SRC: Updated RetrySender to only retry specific status codes. Added status codes to exceptions thrown in StatusCodeSender.

• RetrySender: Only retries specific status codes (specified by the Ruby SDK: 408, 429, 500, 502, 503, 504)
• StatusCodeSender: Added status codes to exceptions thrown, added new exceptions (RequestTimeoutException and BadGatewayException). Declared $errorMessage variable outside the foreach loop to remove the variable undefined variable error (GitHub issue #40 https://github.com/smartystreets/smartystreets-php-sdk/issues/40)

TESTS: Mostly cosmetic changes

• International Autocomplete ClientTest: Added require SmartyException
• Mocks: Changed exceptions thrown when a retry is needed to MustRetryException to ensure that the request is retried. We can also change this to be another exception class that is retried (408, 429, 500, 502, 503, 504) but I decided to just make a new exception class for now. We can change that
• RetrySenderTest: Added require MustRetryException
• StatusCodeSenderTest: Added use statements for exceptions and removed \SmartyStreets\PhpSdk\Exceptions\ from the beginning of each exception class type. I can also revert this. Changed test402ResponsePThrowsPaymentRequiredException test name to remove the extra P in the name
