Function New-AzureLab {
  <#
    .SYNOPSIS
    New-AzureLab will create 1 or multiple VMs in Azure based on input parameters from a CSV

    .DESCRIPTION
    Create a CSV file like below:
    VMName,Location,InterfaceName,ResourceGroupName,VMSize,ComputerName
    SP,EastUS,SP_Int,SignalWarrant_RG,Basic_A2,SP

    The function will read the input from the CSV file and create VMs in an Azure Resource Group
    
    .PARAMETER csvpath
    The full path to your CSV file (eg c:\scripts\VMs.csv)

    .EXAMPLE
    New-AzureLab -csvpath c:\scripts\VMs.csv
    Imports the applicable values from the CSV file

    .NOTES
    1. I already had a Resource Group in Azure therefore I put all the VMs in the same group.
    2. I already had a VM network created, all my VMs are in the same network.
