<#
    .SYNOPSIS
        Create valid runbook file based on the task passed as inputs
         
    .DESCRIPTION
        Helps you build a valid runbook file, based on all the individual tasks that are passed as inputs
         
        This makes it easy to get a starting point for a new runbook file, based on the tasks you have build in your array and then passes into the cmdlet
         
        Tasks are expected to be the ones that are part of the module
         
    .PARAMETER Task
        Names of the tasks that you want to be part of your runbook file
         
        Supports array of task names
         
        Names of the different tasks are expected to be the ones that are part of the module
         
    .PARAMETER SubscriptionId
        Id of the subscription that you want to work against
         
        At runtime / execution of Invoke-PsLaExtractor - your current powershell / az cli session either needs to be "connected" to the subscription or at least have permissions to work against the subscription
         
        Useful when you know upfront what you want to work against, as you don't need to pass the parameter into the Invoke-PsLaExtractor
         
    .PARAMETER ResourceGroup
        Name of the resource group that you want to work against
         
        At runtime / execution of Invoke-PsLaExtractor - your current powershell / az cli session needs to have permissions to work against the resource group
         
        Useful when you know upfront what you want to work against, as you don't need to pass the parameter into the Invoke-PsLaExtractor
         
    .PARAMETER Name
        Name of the logic app, that you want to work against
         
        At runtime / execution of Invoke-PsLaExtractor - your current powershell / az cli session needs to have permissions to work against the logic app
         
        Useful when you know upfront what you want to work against, as you don't need to pass the parameter into the Invoke-PsLaExtractor
         
    .PARAMETER OutputPath
        Path to were the runbook file will be persisted
         
        The path has to be a directory
         
        The runbook file will be named: PsLaExtractor.default.psakefile.ps1
         
    .PARAMETER IncludePrefixSuffix
        Instruct the cmdlet to add the different prefix and suffix options, with the default values that comes with the module
         
        This make it easier to make the runbook file work across different environments, without having to worry about prepping different prefix and suffix value prior
         
    .EXAMPLE
        PS C:\> New-PsLaRunbookByTask -Task "Export-LogicApp.AzCli","ConvertTo-Raw","ConvertTo-Arm"
         
        Creates a valid runbook file, based on the bare minimum and with sane default values
        Will write the include and taskList in the mentioned order of the tasks
         
    .EXAMPLE
        PS C:\> New-PsLaRunbookByTask -Task "Export-LogicApp.AzCli","ConvertTo-Raw","ConvertTo-Arm" -SubscriptionId "f5608f3d-ab28-49d8-9b4e-1b1f812d12e0" -ResourceGroup "TestRg"
         
        Creates a valid runbook file, based on the bare minimum and with sane default values
        Will write the include and taskList in the mentioned order of the tasks
        Prepares the Properties object with SubscriptionId and ResourceGroup
         
        Useful if you have multiple logic apps in the same resource group and you want them extracted using the same runbook file
         
    .EXAMPLE
        PS C:\> New-PsLaRunbookByTask -Task "Export-LogicApp.AzCli","ConvertTo-Raw","ConvertTo-Arm" -SubscriptionId "f5608f3d-ab28-49d8-9b4e-1b1f812d12e0" -ResourceGroup "TestRg" -Name "TestLogicApp"
         
        Creates a valid runbook file, based on the bare minimum and with sane default values
        Will write the include and taskList in the mentioned order of the tasks
        Prepares the Properties object with SubscriptionId and ResourceGroup and Name
         
        Useful if you want to have a ready to run runbook file, that makes it simple to run the command again and again
        Great for iterative work, where you make lots of small changes in the logic app and want to see how the changes affect your ARM template
         
    .EXAMPLE
        PS C:\> New-PsLaRunbookByTask -Task "Export-LogicApp.AzCli","ConvertTo-Raw","ConvertTo-Arm" -OutputPath c:\temp\PsLaRunbooks
         
        Creates a valid runbook file, based on the bare minimum and with sane default values
        Will write the include and taskList in the mentioned order of the tasks
        Outputs the build to c:\temp\PsLaRunbooks
         
        The runbook file is default named: PsLaExtractor.default.psakefile.ps1
         
    .EXAMPLE
        PS C:\> New-PsLaRunbookByTask -Task "Export-LogicApp.AzCli","ConvertTo-Raw","ConvertTo-Arm" -IncludePrefixSuffix
         
        Creates a valid runbook file, based on the bare minimum and with sane default values
        Will write the include and taskList in the mentioned order of the tasks
        The Properties object inside the runbook file, will be pre-populated with the default prefix and suffix values from the module
         
        This make it easier to make the runbook file work across different environments, without having to worry about prepping different prefix and suffix value prior
