Increase flexibility in API-url replacement

[seriema]

Currently apiMock simply does a string.replace to change apiPath into mockDataPath.

Two other options could be added:

1. Use a regex for apiPath.
2. Use a method for mockDataPath.

Does anyone really want this or was I just feature-creeping?

+1, excellent work, I thought on being backward compatibility being able to handle an array of strings and/or regexs leaving simple string to not get a breaking change.

By the way the only issue I have is only work with true option, don't work if I use auto or number for status code.
Even not working in demo http://johansson.jp/angular-apimock/#/demo-simple?apimock=auto

@Wolfium I created an issue for the bug you reported: #37 Feel free to add any details if you'd like.
