how to figure out what values are located where:

# figure out what indexes contract variables lie (prints first 15 indexes)
function hex2a(hexx) {
    var hex = hexx.toString();//force conversion
    var str = '';
    for (var i = 0; i < hex.length; i += 2)
        str += String.fromCharCode(parseInt(hex.substr(i, 2), 16));
    return str;
}
for (var i=0; i<15; i++){
    var hex_str = (await eth.getStorageAt('0xB6eD7644C69416d67B522e20bC294A9a9B405B31', i, 5280486)).toString();
    hex_str = hex_str.substr(2, 64);
    
    console.log(i, hex_str);
    console.log('    u256(int):', new Eth.BN(hex_str, 16).toString(10));
    console.log('    u128[0](int):', new Eth.BN(hex_str.substr(0,32), 16).toString(10));
    console.log('    u128[1](int):', new Eth.BN(hex_str.substr(32,64), 16).toString(10));
    try { 
        console.log('    u256(str):', hex2a(hex_str));
        } catch(err) {
