    <#
    .SYNOPSIS
    Ensures specific Event Log Sources exist.
 
    .DESCRIPTION
    This function should be invoked remotely (with -RunRemotely).
    It uses following tokens:
    - **EventLogSources** - hashtable or array of hashtables in form @{ Name = <event log source name> (required); LogName = <log name> (optional) }
 
    See also [[New-EventLogSource]].
 
    .PARAMETER Tokens
    (automatic parameter) Tokens hashtable - see description for details.
 
    .EXAMPLE
    ```
    Import-Module "$PSScriptRoot\..\PSCI\PSCI.psd1" -Force
 
    # clear any old Environment definitions - required only for -NoConfigFiles deployments
    $Global:Environments = @{}
 
    Environment Local {
        ServerConnection WebServer -Nodes localhost
        ServerRole Web -Steps 'PSCIEventLogSource' -ServerConnection WebServer
 
        Tokens Web @{
            EventLogSources = @(
                @{ Name = 'MyEventLogSource' },
                @{ Name = 'MyEventLogSource2'; LogName = 'MyLogName' }
            )
        }
    }
 
    try {
        Start-Deployment -Environment Local -NoConfigFiles
    } catch {
