.SYNOPSIS
Use this cmdlet to host files for download. The idea of this is to have a PowerShell SimpleHTTPServer that is similar to Python's SimpleHTTPServer module.
.DESCRIPTION
Running this function will open a PowerShell web server hosting files in the current directory. The server can be accessed at http://localhost:8000 You can download files. The directories are not able to be traversed through the web server.
.PARAMETER Port
The port parameter is for easily defining what port the http server should listen on. The default value is 8000.
.EXAMPLE
Start-SimpleHTTPServer
# This example starts an HTTP server on port 8000 in the current directory.
.EXAMPLE
Start-SimpleHTTPServer -Port 80
# This example starts an HTTP server on port 80 in the current directory.
