Provides:

```javascript
{
    code: {
        CodeManager: CodeManager,
        BreakpointManager: BreakpointManager
    },
    storage: {
        StorageViewer: StorageViewer,
        StorageResolver: StorageResolver
    },
    trace: {
        TraceManager: TraceManager
    }
}
```
      

TraceManager is a convenient way to access a VM Trace and resolve some value from it.

`TraceManager()` :

`function resolveTrace(stepIndex, tx)`

`function init(stepIndex, tx)`

`function inRange(stepIndex, tx)`

`function isLoaded(stepIndex, tx)`

`function getLength(stepIndex, tx)`

`function accumulateStorageChanges(stepIndex, tx)`

`function getAddresses(stepIndex, tx)`

`function getCallDataAt(stepIndex, tx)`

`function getCallStackAt(stepIndex, tx)`

`function getStackAt(stepIndex, tx)`

`function getLastCallChangeSince(stepIndex, tx)`

`function getCurrentCalledAddressAt(stepIndex, tx)`

`function getContractCreationCode(stepIndex, tx)`

`function getMemoryAt(stepIndex, tx)`

`function getCurrentPC(stepIndex, tx)`

`function getReturnValue(stepIndex, tx)`

`function getCurrentStep(stepIndex, tx)`

`function getMemExpand(stepIndex, tx)`

`function getStepCost(stepIndex, tx)`

`function getRemainingGas(stepIndex, tx)`

`function getStepCost(stepIndex, tx)`

`function isCreationStep(stepIndex, tx)`

`function findStepOverBack(stepIndex, tx)`

`function findStepOverForward(stepIndex, tx)`

`function findStepOverBack(stepIndex, tx)`

`function findNextCall(stepIndex, tx)`

`function findStepOut(stepIndex, tx)`

`function checkRequestedStep(stepIndex, tx)`

`function waterfall(stepIndex, tx)`
