/**
 * A instance of Process represents a stateful process executing a series of Tasks, 
 *  which may be:
 *  <ul>
 *  <li> user interactions
 *  <li> calls to DataSources (hence: any database or web service)
 *  <li> arbitrary code
 *  <li> other Processes
 *  </ul>
 * A Process is <i>stateful</i> in the sense that it maintains {@link com.smartgwt.client.util.workflow.Process#getState
 * state}
 *  across the different tasks that are executed.  This allows you to maintain context as you
 *  walk a user through a multi-step business process in your application, which may involve
 *  multiple operations on multiple entities.  Each Task that executes can use the Process state
 *  as inputs, and can output a result which is stored in the Process state - see
 *  {@link com.smartgwt.client.docs.TaskIO}.
 *  <P>
 *  A Process can have multiple branches, choosing the next Task to execute based on
 * {@link com.smartgwt.client.data.Criteria} - see {@link com.smartgwt.client.util.workflow.DecisionTask} and {@link
 * com.smartgwt.client.util.workflow.MultiDecisionTask}.
 *  <P>
 *  Because a Process may return to a previous Task in various situations, the data model of a
 *  Process is strictly speaking a <i>graph</i> (a set of nodes connected by arbitary
 *  interlinks). However, most processes have sequences of several tasks in a row, and the
 *  definition format allows these to be represented as simple Arrays called "sequences",
 * specified via {@link com.smartgwt.client.util.workflow.Process#getSequences sequences}.  This reduces the need to
 * manually specify IDs and
 *  interlinks for Tasks that simply proceed to the next task in a sequence.
 *  <P>
 *  Processes follow all the standard rules for encoding as {@link com.smartgwt.client.docs.ComponentXML}, however,
 * note that the &lt;Process&gt; tag allows any kind of {@link com.smartgwt.client.util.workflow.ProcessElement} (tasks,
 * decisions
 *  and sequences) to appear as a direct subelement of the &lt;Process&gt; tag without the need
 *  for an intervening &lt;elements&gt; or &lt;sequences&gt; tag.  The example below
 *  demonstrates this shorthand format.
 *  <pre>
 *  &lt;Process ID="<i>processId</i>"&gt;
 *      &lt;DSRequestTask ID="<i>dsRequestTaskId</i>" nextElement="<i>sequenceId</i>" ..&gt;
 *          &lt;inputFieldList&gt;
 *              &lt;value&gt;order.countryName&lt;/value&gt;
 *          &lt;/inputFieldList&gt;
 *          &lt;outputFieldList&gt;
 *              &lt;value&gt;order.countryName&lt;/value&gt;
 *              &lt;value&gt;order.continent&lt;/value&gt;
 *          &lt;outputFieldList&gt;
 *      &lt;/DSRequestTask&gt;
 *      &lt;sequence ID="<i>sequenceId</i>" &gt;
 *          &lt;StateTask ../&gt;
 *          &lt;StateTask ../&gt;
 *          &lt;StateTask ../&gt;
 *          &lt;StateTask nextElement="<i>userTaskId</i>" ../&gt;
 *      &lt;/sequence&gt;
 *      &lt;UserTask ID="<i>userTaskId</id>" ../&gt;
 *      ...
 *  &lt;/Process&gt;
 *  </pre>
 *  <b>NOTE:</b> you must load the standard DataBinding module before you can use <code>Process</code>.
