ruby hash pretty print to console

Readme.md

my_pretty_print module

###example: ####0. Initialize your hash:

h = {some: 1, "the" => {subone: "true", subtwo: [1,2,"3333", {subsub: "one", nonenone: {twotwo: [{keyone: 1, keytwo: ["222","sdsd"]},1,2], some: "free"}}]}, ne: "xt"}

####1. simple:

h.my_pretty_print

####2. print only one key:

h.my_pretty_print selector: "the"
h.my_pretty_print selector: :one

####3. print by index:

h.my_pretty_print selector: 1

####4. print by range:

h.my_pretty_print selector: 0..1
