Can we separate the different parts of this and unblock 3.6.0?
Is the following acceptable for 3.6.0:
1. #314 fixed a specific problem - `<file:filename>` and "filename" behave
differently for resolution when the assembler file is not in the current
directory of the JVM as happens in Fuseki.
1. Make `ja:MemoryDataset` the class for the TIM assembler, with
`ja:DatasetTxnMem` registered for backwards compatibility.
1. Add the Fuseki example for using `ja:MemoryDataset`.
