Returns a collection of file ranges and their starting and ending byte offsets using the specified request
options and operation context.

@param accessCondition
An {@link AccessCondition} object which represents the access conditions for the file.
@param options
A {@link FileRequestOptions} object that specifies any additional options for the request. Specifying
<code>null</code> will use the default request options from the associated service client (
{@link CloudFileClient}).
@param opContext
An {@link OperationContext} object which represents the context for the current operation. This object
is used to track requests to the storage service, and to provide additional runtime information about
the operation.

@return An <code>ArrayList</code> object which represents the set of file ranges and their starting
and ending byte offsets.

@throws StorageException
If a storage service error occurred.
