    .SYNOPSIS
        This script launches a remote console session in your default browser for a vSphere/ESXi VM.
    .DESCRIPTION
        This requires PowerCLI v5.0 or greater, Adobe Flash, and the VMware client integration/Remote 
        console plug-in installed (vmware-vmrc-win32-x86.exe) in order to function. Adapted from 
        William Lam and Dylan Thompson.
    .PARAMETER VMName
        The name of the VM as known by vCenter.
    .PARAMETER VCName
        The name of the vCenter. Needed to perform all actions related to the VM.
    .PARAMETER VCUser
        User that is authorized to login to vCenter
    .PARAMETER VCUserPwd
        The password for the vCenter user
