+This script helps to get the impersonator and impersonated user details and duration of impersonation.
+
+
+Details of Events:
+
+(impersonation.start) which shows that the impersonation has started, 
+(impersonation.end) shows that the impersonation has ended.
+
+Parm1 contains the userid of user who started the impersonation.
+Parm2 contains the userid of user whom we have impersonated.
