A BlobBuilder is a helper object for creating Blobs.
A Blob is an immutable, read-only object, the same as a JavaScript string. BlobBuilders are used to generate a Blob with new content. They are to Java's StringBuilder as Gears Blobs are to Java's Strings.
The BlobBuilder API does not require user permission.
