Function Start-WHAM{
<#
    .SYNOPSIS
    Launch / download WHAM and its dependancies
     
    .DESCRIPTION
    Function to control the download and execution of WHAM. 
    By default the function will cache all WHAM files to `$env:tmp and execute it from there. The cache will last for 24 hours
    If you run the function and the cache is already present, it will just run WHAM (unless cache is over 24 hours old)
    
    .PARAMETER Download
    Description: Forces a fresh download of WHAM to `$ENV:tmp
    Example use: Start-WHAM -Download
    
    .PARAMETER DC
    Description: Specify the DC to download WHAM. Without this param we default to the closest one via the DC key
    Example use: Start-WHAM -DC ORD
    
    .PARAMETER NoRun
    Description: Will not launch WHAM - useful just to cache files and work with `$env:tmp directly
    Example use: Start-WHAM -NoRun -Download
    
    .PARAMETER Dev
    Description: Runs WHAM in DEV mode, downloads from DEV location, doesnt log to AppStats and turns on verbose output
    Example use: Start-WHAM -Dev

    .PARAMETER CustomWHAMParams
    Description: Pass through a blob of WHAM params. I wouldnt really do this, use -NoRun then browse to `$env:tmp and interact with Wham_controller.ps1 directly
    Example use: Start-WHAM -CustomWHAMParams @{Devices="502664,502667"}

    .EXAMPLE
    Full command: Start-WHAM -DC ORD -Download -NoRun
    Description: Download WHAM to `$env:tmp from the ORD media server but dont run
    
    .EXAMPLE
    Full command: Start-WHAM -Dev 
    Description: Launch WHAM in dev mode
