Filter the query on the period_begin column

Example usage:
<code>
$query->filterByPeriodBegin('2011-03-14'); // WHERE period_begin = '2011-03-14'
$query->filterByPeriodBegin('now'); // WHERE period_begin = '2011-03-14'
$query->filterByPeriodBegin(array('max' => 'yesterday')); // WHERE period_begin > '2011-03-13'
</code>

@param     mixed $periodBegin The value to use as filter.
Values can be integers (unix timestamps), DateTime objects, or strings.
Empty strings are treated as NULL.
Use scalar values for equality.
Use array values for in_array() equivalent.
Use associative array('min' => $minValue, 'max' => $maxValue) for intervals.
@param     string $comparison Operator to use for the column comparison, defaults to Criteria::EQUAL

@return ChildDealerShedulesVersionQuery The current query, for fluid interface
