reassign .this to a fixed object for methods
npm install @importvault/bindallob - Object to bind methods to.
fns - is an object whose values get fixed bound to ob
selected - Array of string providing names of selected functions to bind - in case when binding needs to be done selectively.
npm install @importvault/bindall
`
#### Internals
- reassign `.this` to fixed object for selected functions
- mutates fns that holds the functions
- Other implementation ( lodash, underscore ) of bindall does not provide option to control what fns is bound to.
- 40 lines of code.

}
var ob =
{
fuel:"coffee",
fns:
{
foo:log
}
}
ob.fns.foo() // { foo: [Function: foo] } // cannot access .fuel :(
bindall(ob,ob.fns) // will mutate original object
ob.fns.foo()
// { fuel: 'coffee', fns: { foo: [Function] } } // can access .fuel now !
