<<includes>> or <<uses>> Here both the use cases should be
satisfied or the return value of one use case will affect
the other.
e.g : Let us take the ATM cash withdrawal. actor -> inserts
card -> enters pin ---<<includes>>--->Verify card.
Here if the second use case returns false ie verification
fails, then the first use case follow the alternate flow or
error flow. It will not continue the regular flow.
<<extends>> Here one use case invoke other. thats all.
