sessionManager - sessionStorage/localStorage manager - Stores and retrive data from objects

readme.md

#sessionManager // Stores and retrive data from objects like an orm style

window.session = sessionManager(sessionStorage,'reserva','-', reserva);

console.log(session()); // Get the main data object

session('hello-world','hola mundo') // sets the value of {hello:{world: 'hola mundo'}} its the same as reserva.hello.world = 'hola mundo'

console.log(session('hello-world')) // returns 'hola mundo' and its the same as reserva.hello.world
