Trivial Last In First Out (LIFO) tracker with transfer function.
Usage
const LedgerLIFO = require('ledger-lifo');
var myLIFO = new LedgerLIFO();
var acct1 = '12345'; //acct identifiers can be any string allowed as an object property name
var acct2 = '67890';
var acct3 = '71337';
// all properties except f (from acct) and t (to acct) are tracked
// it is up to the developer to choose properties to track, give them meaning, and decide when to override a property
myLIFO.transfer({f:acct1, t:acct2, v:100, unitcost:3});
myLIFO.transfer({f:acct1, t:acct2, v:300, unitcost:5});
// myLIFO.accounts[acct2] === [{v:300, unitcost:5}, {v:100, unitcost:3}]
myLIFO.transfer({f:acct2, t:acct3, v:350});
// myLIFO.accounts[acct2] === [{v:50, unitcost:3}]
// myLIFO.accounts[acct3] === [{v:50, unitcost:3}, {v:300, unitcost:5}]
