function Test-CRegistryKeyValue
{
<#
.SYNOPSIS
Tests if a registry value exists.
.DESCRIPTION
The usual ways for checking if a registry value exists don't handle when a value simply has an empty or null value. This function actually checks if a key has a value with a given name.
.EXAMPLE
Test-CRegistryKeyValue -Path 'hklm:\Software\Carbon\Test' -Name 'Title'
Returns `True` if `hklm:\Software\Carbon\Test` contains a value named 'Title'. `False` otherwise.

param(
[Parameter(Mandatory=$true)]
[string]
# The path to the registry key where the value should be set. Will be created if it doesn't exist.
$Path,
[Parameter(Mandatory=$true)]
[string]
# The name of the value being set.
$Name
