The EVIDENCE_COMPARE Widget

The EVIDENCE_COMPARE widget displays the differences between two sets of evidence. These differences are high-lighted using the following colors: evidence items that have changed are shown in red; new items are shown in green; deleted items are shown in gray.

This widget should be the sole element in a CLUSTER. Its TYPE should be set to EVIDENCE_COMPARE and its WIDGET_PARAMETER elements should be set as follows:
