stringslice

Adds functions to string slices:

• Sort (does not mutate)
• Uniq (currently implies also sorted)
• Map
• Reduce (aka inject)
• Subtract (subtract one slice's elements from another slice and return the result)
• Add (add two slices together and return the result)
• Contains
• Index

Future support; perhaps (let me know if you'd like to see one of these – @ssoroka on twitter):

• compact (remove nils)
• reject (aka delete_if)
• select (aka filter)
• each
• join (alias from strings.Join)
• pop
• push
• shift
• unshift
• reverse
• sort_by (like sort, but you can give the sorting function)

usage

  s := []string{"echo", "alpha", "bravo", "delta", "charlie", "Charlie"}

  s2 := stringslice.New(s).Sort().Map(func(i int, s string) string {
    return strings.ToUpper(s)
  }).Subtract([]string{"ALPHA"}).Uniq().Slice()

  fmt.Println(s2)

prints out [BRAVO CHARLIE DELTA ECHO]
