Storing and retrieving a string

The DataShare class enables a virtual user to store a string value in one test and then retrieve it in a different test.
package test;

import com.ibm.rational.test.lt.kernel.IDataArea;
import com.ibm.rational.test.lt.kernel.services.ITestExecutionServices;

/**
 * The DataShare class enables a virtual user to store a string value in one
 * test and then retrieve it in a different test.  The "first" test would
 * need to include this custom code and call it with a single argument - the
 * string that is to be stored.  The subsequent tests would include the
 * same custom code but would call it with no arguments; it will return the
 * stored string value.  The class also prints messages in the test log
 * detailing its operation.
