function Set-PSFFeature
{
<#
    .SYNOPSIS
        Toggles a feature on or off.
     
    .DESCRIPTION
        Toggles a feature on or off.
        This controls the flags for optional features a module might offer.
     
        Features can be controlled globally or specific to a module that tries to consume it.
        Module specific settings can override global settings, if a feature supports both global and module flags.
     
    .PARAMETER Name
        The name of the feature to set.
     
    .PARAMETER Value
        The value to set it to.
     
    .PARAMETER ModuleName
        The module it should apply to.
        Specifying this parameter sets the flag only for the module specified.
     
    .EXAMPLE
        PS C:\> Set-PSFFeature -Name 'PSFramework.InheritEnableException' -Value $true -ModuleName SPReplicator
     
        This sets the flag for the Enable Exception Inheritance Name to $true, but only applies to the module SPReplicator.
     
    .EXAMPLE
        PS C:\> Set-PSFFeature -Name 'MyModule.Feierabend' -Value $true
     
        This enables the global flag for the MyModule.Feierabend feature.
