com.google.api.client.googleapis.MethodOverride
HTTP request execute interceptor for Google API's that wraps HTTP requests -- other than GET or POST -- inside of a POST request and uses {@code "X-HTTP-Method-Override"} header to specify theactual HTTP method.
Use this for an HTTP transport that doesn't support PATCH like {@code NetHttpTransport} or{@code UrlFetchTransport}. By default, only the methods not supported by the transport will be overridden. When running behind a firewall that does not support certain verbs like PATCH, use the {@link MethodOverride#MethodOverride(EnumSet)} constructor instead to specify additionalmethods to override. GET and POST are never overridden.

Sample usage, taking advantage that this class implements {@link HttpRequestInitializer}:
```
 public static HttpRequestFactory createRequestFactory(HttpTransport transport) { return transport.createRequestFactory(new MethodOverride()); } 
```
If you have a custom request initializer, take a look at the sample usage for {@link HttpExecuteInterceptor}, which this class also implements.
