Tools do not work with ollama

[ColtonMcInroy]

Changing the example MiddleSchoolMathAgent.ts from openai to ollama results in the following error:
TypeError: model.doGenerateToolCalls is not a function

With Ollama, you need to specify how you go from text output to tools. There are some examples here: https://github.com/lgrammel/modelfusion/tree/main/examples/basic/src/model-provider/ollama

E.g.:

 const { tool, args, toolCall, result } = await useTool(
    ollama
      .CompletionTextGenerator({
        model: "mistral",
        promptTemplate: ollama.prompt.Mistral,
        raw: true, // required when using custom prompt template
        format: "json",
        temperature: 0,
        stopSequences: ["\n\n"], // prevent infinite generation
      })
      .withInstructionPrompt()
      .asToolCallGenerationModel(jsonToolCallPrompt.text()),

    new MathJsTool({ name: "calculator" }),
    "What's fourteen times twelve?"
  );

  console.log(`Tool call`, toolCall);
  console.log(`Tool: ${tool}`);
  console.log(`Arguments: ${JSON.stringify(args)}`);
  console.log(`Result: ${result}`);

That being said, chat w/ tools is not supported yet w/ Ollama, and the interface for creating tool models might change.
