This command is used to construct a TimeSeries object in which the load factor is some trigonemtric function of the time in the domain <math> \lambda = f(t) = \begin{cases}
\text{cFactor} * sin (\frac{2.0 \Pi (t-tStart)}{\text{period}} + \text{shift}), &\text{tStart} <= t <= \text{tEnd}\\
\text{0.0}, &\text{otherwise}\\
\end{cases}

| timeSeries Trig $tag $tStart $tEnd $period <-factor $cFactor> <-shift $shift> |
| $tag | unique tag among TimeSeries objects. |
| $tStart | starting time of non-zero load factor |
| $tEnd | ending time of non-zero load factor |
| $period | characteristic period of sine wave |
| $shift | phase shift in radians (optional, default=0.0) |
| $cFactor | the load factor amplification factor (optional, default=1.0) |
