Description
With new AIMLInterpreter(botAttributes) one can create a new interpreter object. botAttributes is an JSON-Object that can contain attributes of the bot one wants to use in AIML files, e.g. ({name: "Bot", age:"42"}).
This object has a function called loadAIMLFilesIntoArray(fileArray) which receives an array of AIML files. This function loads the AIML file into memory.
Furthermore, the object has a function called findAnswerInLoadedAIMLFiles(clientInput, cb) which receives a message and a callback. The callback is called when an answer was found. The callback of findAnswerInLoadedAIMLFiles should look like this: callback(result, wildCardArray, input). Result is the answer from the AIML file and wildCardArray stores the values of all wildcardInputs passed previously from the client. The original input which triggered the answer is given back via input.

Example:

AIMLInterpreter = require('./AIMLInterpreter');
var aimlInterpreter = new AIMLInterpreter({name:'WireInterpreter', age:'42'});
aimlInterpreter.loadAIMLFilesIntoArray(['./test.aiml.xml']);
var callback = function(answer, wildCardArray, input){
console.log(answer + ' | ' + wildCardArray + ' | ' + input);
};
aimlInterpreter.findAnswerInLoadedAIMLFiles('What is your name?', callback);
aimlInterpreter.findAnswerInLoadedAIMLFiles('My name is Ben.', callback);
aimlInterpreter.findAnswerInLoadedAIMLFiles('What is my name?', callback);
