filter Test-IsNull {
	<#
.SYNOPSIS
	Simple Null Coalesce Filter
.PARAMETER ValueA
	Value to test for null. Returns this if it's not.
.PARAMETER ValueB
	Value to return if ValueA is null
.PARAMETER Strict
	Correctly handle the case where ValueA is $false.
.DESCRIPTION
	Test if ValueA is null, and return ValueB if so. The legacy version mishandled the case where ValueA is $false.
	The Strict flag was added as some existing functionality depends on that mishandling.

		$ValueA,

	} else {
		Write-Warning "$logLead : You are using the old version of this function. Unless you're counting on `$false being equivalent to `$null, you should add the `$Strict flag."
		if ($null -ne $ValueA -and $ValueA -ne "") { $ValueA } else { $ValueB }
