Functions

isBlob(input) ⇒ Boolean

Returns a boolean telling if value is blob or
not

isArrayBuffer(input) ⇒ Boolean

Returns a boolean telling if value is any of
the ArrayBuffer view or not

Callback will be called with error, if outputFormat is invalid
or input is not a blob.

parseArrayBuffer(input) ⇒ String

Parses the arrayBuffer to a string
