mid-item matching

[jiaaro]

In AddGroceryView

"cr" should match "cranberries" and "dried cranberries" and "raisins/cranberries" and "orange-cranberry cocktail"

from learn swift online:

var myString = "One-Two-Three-1 2 3"
var array : String[] = myString.componentsSeparatedByCharactersInSet(NSCharacterSet (charactersInString: "- "))
//Returns ["One", "Two", "Three", "1", "2", "3"]
