/**
 * Simple Matlab interface for openBIS for Screening. It is meant to be used in one Matlab session
 * at a time, i.e. it is <i>not</i> multi-threading safe.
 * <p>
 * While written in Java, the API is idiomatic for Matlab, i.e. values are returned as
 * multi-dimensional arrays. For the <code>get...</code> and <code>load...</code> methods the first
 * index will contain the actual data, while the second index will contain per-row annotations. For
 * <code>getFeatureMatrix</code>, the third index contains per-column annotations. This allows
 * simple access with Matlab's slicing operator, see doc of e.g. {@link #getFeatureMatrix(String)}.
 * <p>
 * A typical Matlab session looks like:
 * 
 * <pre>
 * % 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()
 * </pre>
 * 
 * <i>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.</i>
 * <p>
 * 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 <b>code</b>, which is unique only in
 * the context of the parent.<br>
 * That's why one needs <b>augmented code</b> to point e.g. to one experiment, because two different
 * projects can have experiments with the same code.<br>
 * Such an augmented code for experiment has a form of "/space-code/project-code/experiment-code".<br>
 * For plate it has a form of "/space-code/plate-code" (note that plate code is unique on the space
 * level). <br>
 * 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 <b>perm id</b> (permament identifier) which never
 * change and allow to refer to them with one "magic" identifier, e.g. 20110516124520378-737166.
 * </p>
