Monkey-patches for filesystem related things.

• Rewrite require function to load Node's modules from memory.
• Or rewrite the whole fs filesystem module.

npm install --save fs-monkey

An fs-like object is an object that implements methods of Node's filesystem API. It is denoted as vol:

let vol = {
    readFile: () => { /* ... */ },
    readFileSync: () => { /* ... */ },
    // etc...
}

• patchFs - rewrites Node's filesystem module fs with fs-like object vol
• patchRequire - rewrites require function, patches Node's module module to use a given fs-like object for module loading
