Write a program that will correctly format the items we're taking on our picnic. For one item, it should print the one item.
PS C:\> .\picnic.ps1 sandwiches
You are bringing sandwiches.
For two items, place "and" in between:
PS C:\> .\picnic.ps1 sandwiches chips
You are bringing sandwiches and chips.
For three or more items, use commas and "and":
PS C:\> .\picnic.ps1 sandwiches chips cake
You are bringing sandwiches, chips, and cake.
If the -sorted flag is present, the items should first be sorted:
PS C:\> .\picnic.ps1 sandwiches chips cake -sorted
You are bringing cake, chips, and sandwiches.
