.SYNOPSIS
Installer for Lepton

.DESCRIPTION
Installs Lepton onto selected Firefox profiles

.INPUTS
TODO: input directories for installation?
Would need to discuss a non-interactive install system

.OUTPUTS
TODO: output directories that Lepton has been installed to?

.PARAMETER u
Specifies whether to update a current installation
Defaults to false

.PARAMETER f
Specifies a custom path to look for Firefox profiles in

.PARAMETER p
Specifies a custom name to use when creating a profile

.PARAMETER h
Shows this help message

.PARAMETER ?
Shows this help message

.PARAMETER WhatIf
Runs the installer without actioning any file copies/moves
Equivelant to a dry-run

.EXAMPLE
PS> .\Install.ps1 -u -f C:\Users\someone\ff-profiles
Updates current installations in the profile directory 'C:\Users\someone\ff-profiles'
