        Note: Each time you update a subnet you must change its name.
     
    .PARAMETER Category
        The category the subnet should have.
     
    .PARAMETER Subnets
        The IP ranges assigned to this subnet
     
    .PARAMETER Organization
        The Organization the subnet is part of
     
    .PARAMETER Tag
        Any tags the subnet should include

    .EXAMPLE
        PS C:\> Get-MdcaSubnet | Where-Object Name -match "^na_{0,1}$" | Set-MdcaSubnet -Subnets '66.66.66.0/24' -Name { ($_.Name + "_") -replace "__" }
         
        Updates the subnet na to _only_ include the iprange '66.66.66.0/24'.
