Success conditions:
All functions pass test.

Failure conditions:
Any function fails.

Client was active but shouldn't be yet
Client was not active but should be
Could not connect the client
Mismatch between guidList size and systemList size 
NumberOfConnections problem
SystemList problem with GetSystemList
Both SystemList and Number of connections have problems and report different results
Both SystemList and Number of connections have problems and report same results
Undefined Error
System address from list is wrong.
Guid from list is wrong
GetSystemAddressFromIndex failed to return correct values
GetSystemAddressFromGuid failed to return correct values
GetGuidFromSystemAddress failed to return correct values
GetGUIDFromIndex failed to return correct values
GetExternalID failed to return correct values
