Test cases for Disintegration of Plate

[yuriy0]

The Maple simplifier is close to being able to tackle arrays; test cases are needed for this to happen. There is at least one in DisintT (helloWorld); there are potential sources of more tests:

• Programs in examples/icfp2017 as compared to the output of the Haskell disintegrator.

• Generalizing existing Maple test cases to multiple, fixed dimension (i.e. HReal -> Pair(HReal, HReal)) and to arrays of arbitrary dimension (HReal -> HArray HReal).
