      public class Criterion
      extends Criteria

  An object representing a criterion to apply to a record.

  A criterion is part of the definition of an `AdvancedCriteria` object, which is used to filter records according to search criteria.

  A criterion consists of an `operator` and typically a `fieldName` from a `Record` and a `value` to compare to. However some operators either don't require a value (eg, isNull) or act on other criteria rather than directly on a `Record`'s fields (eg, the "and" and "or" logical operators).

  A shortcut form is also allowed where only `fieldName` and `value` values are provided. In this case the `operator` is assumed to be "equals".

          public void addCriteria(Criterion c)

      Adds a new criteria.

      If the present criteria operation is "and", the new criteria is appended to the criteria list.

      Otherwise, the existing criteria is replaced with an "and" criteria, with two sub-criteria: the existing criteria, and the passed criteria.

      Note that if the existing criteria was empty (as would happen if new AdvancedCriteria() were called with no arguments), an "and" operator will still be introduced, but the passed criteria will be the only sub-criteria.

      To add an additional Criterion when using the "or" operator, use `appendToCriterionList(com.smartgwt.client.data.Criterion)`.

        `c` - the passed criteria object
