* CCompareValidator compares the specified attribute value with another value and validates if they are equal.
*
* The value being compared with can be another attribute value
* (specified via {@link compareAttribute}) or a constant (specified via
* {@link compareValue}. When both are specified, the latter takes
* precedence. If neither is specified, the attribute will be compared
* with another attribute whose name is by appending "_repeat" to the source
* attribute name.
*
* The comparison can be either {@link strict} or not.
*
* Starting from version 1.0.8, CCompareValidator supports different comparison operators.
* Previously, it only compares to see if two values are equal or not.
