+    .SYNOPSIS
+        Check the status of VM Replications.
+
+    .DESCRIPTION 
+        This script will check the replication status on VM's primairy and secondairy replication on the host the script is running on,
+        This script should be deployed as a Check Script. 
+
+    .OUTPUTS
+        Errorcodes: 
+        0 - All OK
+        1 - There is an error in one of the replications
