* While written in Java, the API is idiomatic for Matlab, i.e. values are returned as
* multi-dimensional arrays. For the get... and load... methods the first
* index will contain the actual data, while the second index will contain per-row annotations. For
* getFeatureMatrix, the third index contains per-column annotations. This allows
* simple access with Matlab's slicing operator, see doc of e.g.
* {@link #getFeatureMatrix(String, String, String[])}.
*
* A typical Matlab session looks like: * *
* % Add the API jar file to the classpath
* javaaddpath('/home/brinn/matlab/openbis_screening_api-batteries_included.jar')
* % Login to server
* OpenBISScreeningML.login('user', 'secret', 'https://www.infectome.org')
*
* % ...perform calls on the server...
*
* % Logout to close the session on the server
* OpenBISScreeningML.logout()
*
*
* Note: using this login your password will end up in the Matlab command history. An alternative
* that avoids this is to call the {@link ch.systemsx.cisd.openbis.generic.client.cli.Login} class.
* Logging in on the console will grant this class access to the openBIS server.
*
* To learn the API one needs to understand three basic notions: code, augmented code and perm id.
* Space, project, experiment, plate and well have their own code, which is unique only in
* the context of the parent.
* That's why one needs augmented code to point e.g. to one experiment, because two different
* projects can have experiments with the same code.
* Such an augmented code for experiment has a form of "/space-code/project-code/experiment-code".
* For plate it has a form of "/space-code/plate-code" (note that plate code is unique on the space
* level).
* The drawback of an augmented code is that it's not persistent. If someone e.g. moves the
* experiment from one space to the other augmented code of the experiment becomes invalid. That is
* why experiments, plates and datasets have perm id (permament identifier) which never
* change and allow to refer to them with one "magic" identifier, e.g. 20110516124520378-737166.
*
java.io.tmpdir is
