ValueMatcher (Bedework: Calendar utilities 5.0.0 API)

java.lang.Object
- org.bedework.util.calendar.diff.ValueMatcher

```
public class ValueMatcher
extends Object
```
This class allows comparison of calendaring values. Each value is represented by an iCalendar value-type element (e.g. text, integer). They can be added to the ValueMatcher object and then that object can be compared to another to determine if the values are equal.
