<#
    This PowerShell script is powered by my PSAI and PSAIAgent modules.
    PSAI - Is a port of the OpenAI Python SDK
    PSAIAgent - Is a PowerShell module that allows you turn an OpenAI LLM into an AI Assistant with memory and tools

    Register-Tool - Takes PowerShell functions signatures and creates the JSON to be used by OpenAI 

    New-Agent - Creates an AI Agent that can be used to interact with OpenAI
    Get-AgentResponse - Takes the agent and prompt, calls the OpenAI model, runs the functions if needed and returns the response
