/**
* Implementation of SBML's Trigger construct for Event.
<p>
* An {@link Event} object defines when the event can occur, the variables that are
* affected by the event, and how the variables are affected. The {@link Trigger}
* construct in SBML is used to define a mathematical expression that
* determines when an {@link Event} is <em>triggered</em>.
<p>
* A {@link Trigger} object in SBML Level 2 and Level 3 contains one
* subelement named 'math' containing a MathML expression. The expression
* must evaluate to a value of type <code>boolean.</code> The exact moment at which
* the expression evaluates to <code>true</code> is the time point when the {@link Event} is
* <em>triggered</em>. In SBML Level 3, {@link Trigger} has additional attributes
* that must be assigned values; they are discussed in a separate section
* below.
<p>
* An event only <em>triggers</em> when its {@link Trigger} expression makes the
* transition in value from <code>false</code> to <code>true.</code> The event will also
* trigger at any subsequent time points when the trigger makes this
* transition; in other words, an event can be triggered multiple times
* during a simulation if its trigger condition makes the transition from
* <code>false</code> to <code>true</code> more than once. In SBML Level 3, the behavior
* at the very start of simulation (i.e., at <em>t = 0</em>, where
* <em>t</em> stands for time) is determined in part by the boolean flag
* 'initialValue'. This and other additional features introduced in SBML
* Level 3 are discussed further below.
<p>
* <h2>Version differences</h2>
<p>
* SBML Level 3 Version 1 introduces two required attributes
* on the {@link Trigger} object: 'persistent' and 'initialValue'. The rest of
* this introduction describes these two attributes.
<p>
* <h3>The 'persistent' attribute on {@link Trigger}</h3>
<p>
* In the interval between when an {@link Event} object <em>triggers</em> (i.e.,
* its {@link Trigger} object expression transitions in value from <code>false</code> to
* <code>true</code>) and when its assignments are to be <em>executed</em>, conditions
* in the model may change such that the trigger expression transitions
* back from <code>true</code> to <code>false.</code> Should the event's assignments still be
* made if this happens? Answering this question is the purpose of the
* 'persistent' attribute on {@link Trigger}.
<p>
* If the boolean attribute 'persistent' has a value of <code>true</code>, then once
* the event is triggered, all of its assignments are always performed when
* the time of execution is reached. The name <em>persistent</em> is meant to
* evoke the idea that the trigger expression does not have to be
* re-checked after it triggers if 'persistent'=<code>true.</code> Conversely, if
* the attribute value is <code>false</code>, then the trigger expression is not
* assumed to persist: if the expression transitions in value back to
* <code>false</code> at any time between when the event triggered and when it is to be
* executed, the event is no longer considered to have triggered and its
* assignments are not executed. (If the trigger expression transitions
* once more to <code>true</code> after that point, then the event is triggered, but
* this then constitutes a whole new event trigger-and-execute sequence.)
<p>
* The 'persistent' attribute can be especially useful when {@link Event} objects
* contain {@link Delay} objects, but it is relevant even in a model without delays
* if the model contains two or more events. As explained in the
* introduction to this section, the operation of all events in SBML
* (delayed or not) is conceptually divided into two phases,
* <em>triggering</em> and <em>execution</em>; however, unless events have
* priorities associated with them, SBML does not mandate a particular
* ordering of event execution in the case of simultaneous events. Models
* with multiple events can lead to situations where the execution of one
* event affects another event's trigger expression value. If that other
* event has 'persistent'=<code>false</code>, and its trigger expression evaluates to
* <code>false</code> before it is to be executed, the event must not be executed
* after all.
<p>
* <h3>The 'initialValue' attribute on {@link Trigger}</h3>
<p>
* As mentioned above, an event <em>triggers</em> when the mathematical
* expression in its {@link Trigger} object transitions in value from <code>false</code> to
* <code>true.</code> An unanswered question concerns what happens at the start of a
* simulation: can event triggers make this transition at <em>t = 0</em>,
* where <em>t</em> stands for time?
<p>
* In order to determine whether an event may trigger at <em>t = 0</em>, it
* is necessary to know what value the {@link Trigger} object's 'math' expression
* had immediately prior to <em>t = 0</em>. This starting value of the
* trigger expression is determined by the value of the boolean attribute
* 'initialValue'. A value of <code>true</code> means the trigger expression is
* taken to have the value <code>true</code> immediately prior to <em>t = 0</em>. In
* that case, the trigger cannot transition in value from <code>false</code> to
* <code>true</code> at the moment simulation begins (because it has the value <code>true</code>
* both before and after <em>t = 0</em>), and can only make the transition
* from <code>false</code> to <code>true</code> sometime <em>after</em> <em>t = 0</em>. (To do
* that, it would also first have to transition to <code>false</code> before it could
* make the transition from <code>false</code> back to <code>true.</code>) Conversely, if
* 'initialValue'=<code>false</code>, then the trigger expression is assumed to start
* with the value <code>false</code>, and therefore may trigger at <em>t = 0</em> if
* the expression evaluates to <code>true</code> at that moment.
