Install module if missing

Checks if the given module is already installed - if not – install it (performs Install-Module command).

The module can be used in the PowerShell profile to set up the environment.

To make it fully usable before using it in the profile manual check of this module's existence should be performed.

$installModuleIfMissing=Get-Module -ListAvailable -Name ProductivityTools.InstallModuleIfMissing
if ($installModuleIfMissing -eq $null)
{
    Write-Host "Installing ProductivityTools.InstallModuleIfMissing"
    Install-Module "ProductivityTools.InstallModuleIfMissing" -Force
}
else
{
    Write-Host "`ProductivityTools.InstallModuleIfMissing installed"
}

Instead of using this module, you could use Install-Module all the time, but this work much slower.

The example below shows that a lot of modules already are installed on the computer. One of it ProductivityTools.GetOneDriveDirectory is not installed and this module installs it.
