/app/tool: A new tool for Bing search

[via007]

Title: Add BingSearch Tool for Web Search Functionality

Description:
This PR introduces a new BingSearch class to the project, enabling asynchronous Bing search capabilities as part of the BaseTool ecosystem. The tool allows users to perform web searches on Bing and retrieve a list of relevant URLs based on a given query.

Features:

• Implements BaseTool interface with name, description, and parameters for consistency.
• Uses requests and BeautifulSoup to scrape Bing search results.
• Supports asynchronous execution via asyncio.run_in_executor.
• Returns a list of URLs (up to a specified num_results, defaulting to 10).
• Handles pagination to fetch multiple pages if needed.

Motivation:

This addition expands the project's search capabilities beyond existing tools (e.g., Google Search) by integrating Bing, providing an alternative source for web data. It’s particularly useful for users needing diverse search results or when other search APIs are unavailable.

Implementation:

• The class initializes a requests.Session for persistent HTTP connections.
• The _search_sync method performs the synchronous search logic, wrapped in execute for async support.
• HTML parsing targets Bing’s <ol id="b_results"> and <li class="b_algo"> structure.
• Error handling ensures robustness by returning an empty list on failures.

Usage Example:

from bingsearch import BingSearch
import asyncio

async def main():
    tool = BingSearch()
    results = await tool(query="python", num_results=3)
    for i, url in enumerate(results, 1):
        print(f"{i}. {url}")

asyncio.run(main())

Nice idea! Please update the Agent file as well to integrate this search.
