demo1()

void demo1

Demo1 will just instantiate and object of the passed in type and then execute a save state and print that keywordlist out.

demo2()

void demo2

Save 2 objects to a keywordlist without conflict in values. This will force us to use a prefix in order to save 2 objects to the same list

demo3()

void demo3

(

)

Save object to keywordlist and then pass keyword list to factory and instantitate an object from keywordlist. We will do it twice, the first time without a prefix and then the second time with a prefix.

We will use 2 object types: the first one will be a filter and the second one will be a projection.

Note: you should get identical outputs for both outputs.
