Small syntax compatibility fixes

Multiple output parameters in MATLAB should be divided by a comma.
createAndSetSpots now returns the created spots.
Some changes to createDataset() and setDataVolume() and increased version number to 0.3.2.

(1) createDataset() now returns the created dataset. (2) setDataVolume()
now creates a dataset if it does not exist. (3) Increased version to
0.3.2.
Completed previous commit.
Added a few more tests.
Added check for bounds in getDataSubVolume().

Earlier bounds were not checked and a Java exception would be the
result of asking for a region outside the dataset.
Added test for getSubDataVolume() boundary checks.

Try getting the whole dataset with getSubDataVolume() for both
indexingStart equal to 1 and 0.
Fixed some documentation.
Some corrections in the method documentation.
One more documentation fix.

Forgotten in previous commit.
Small corrections to IceImarisConnectorTestUnit.

Added () to function calls missing them.
Minor name change in IceImarisConnector constructor argument.

Use same nomenclature as in pIceImarisConnector.
Fixed conflict.
Bug fixes.

(1) The property userControl was not always set. (2) startImaris() was
not forcing closure of Imaris.
Force quit in destructor (if UserControl is 1).

The destructor was not forcing closure of Imaris.
