function Get-ArmorCompleteWorkloadTier {
    <#
        .SYNOPSIS
        This cmdlet retrieves the tiers in an Armor Complete workload.
 
        .DESCRIPTION
        Workloads and tiers are logical grouping tools for helping you organize your
        virtual machines and corresponding resources in your Armor Complete
        software-defined datacenters.
 
        Workloads contain tiers, and tiers contain virtual machines.
 
        Workloads are intended to help you describe the business function of a group of
        servers, such as 'My Secure Website', which could be useful for chargeback or
        showback to your customers, as well as helping your staff and the Armor Support
        teams understand the architecture of your environment.
 
        Tiers are intended to describe the application tiers within each workload. A
        typical three tiered application workload is comprised of presentation,
        business logic, and persistence tiers. Common labels for each are: web,
        application, and database respectively, but you can group your VMs however you
        choose.
 
        Returns a set of tiers in a workload that correspond to the filter criteria
        provided by the cmdlet parameters.

        .EXAMPLE
        Get-ArmorCompleteWorkloadTier -WorkloadID 1
        Retrieves the details for all workload tiers in the workload with WorkloadID=1
        in the Armor Complete account that currently has context.
 
        .EXAMPLE
        Get-ArmorCompleteWorkloadTier -WorkloadID 1 -ID 1
        Retrieves the details for the workload tier with ID=1 in the workload with
        WorkloadID=1.
 
        .EXAMPLE
        Get-ArmorCompleteWorkloadTier -WorkloadID 1 -Name 'Database'
        Retrieves the details for the workload tier with Name='Database' in the
        workload with WorkloadID=1.
 
        .EXAMPLE
        2, 3 | Get-ArmorCompleteWorkloadTier -ApiVersion 'v1.0'
        Retrieves the API version 1.0 details for all of the workload tiers in
        workloads with WorkloadID=2 and WorkloadID=3 via pipeline values.
 
        .EXAMPLE
        [PSCustomObject] @{ 'WorkloadID' = 1; 'ID' = 1 } | Get-ArmorCompleteWorkloadTier
        Retrieves the details for the workload tier with ID=1 in the workload with
        WorkloadID=1 via property names in the pipeline.
 
        .EXAMPLE
        [PSCustomObject] @{ 'WorkloadID' = 1; 'Name' = 'Presentation' } | Get-ArmorCompleteWorkloadTier
        Retrieves the details for the workload tier with Name='Presentation' in the
