A light-weight FP utils for Go

## Usage

All functions are group by the data type they are processing, for

example we can `slices.Map` a function to a slice

```go

import "github.com/jcouyang/fp.go/slices"

strLen := func (a1 string) int {

	return len(a1)

}

fmt.Println(

	slices.Map(strLen)([]string{"cat", "catfish", "caterpillar"}),

)

// Output: [3 7 11]

```

Similarily, we can also `Map` the function to a `chan` with `chans.Map`

```go

import "github.com/jcouyang/fp.go/chans"

wordChan := make(chan string, 3)

wordLenChan := chans.Map(strLen)(wordChan)

wordChan <- "cat"

wordChan <- "catfish"

wordChan <- "caterpillar"

	

fmt.Println(

	<-wordLenChan,

	<-wordLenChan,

	<-wordLenChan,

)

// Output: 3 7 11

```
