CoreePower.Module.CreateModule.ps1

<#
.SYNOPSIS
    This function generates a new PowerShell module along with its associated directories, files, and manifest.
 
.DESCRIPTION
    CreateModule is a utility function that automates the process of creating a new PowerShell module.
    It generates essential files like .psm1, .ps1, and a module manifest (.psd1) along with a testing suite.
    It's customizable, allowing you to specify the path, module name, description, and author information.
 
.PARAMETER Path
    Optional. Specifies the directory where the module will be created. Defaults to the current location.
 
.PARAMETER ModuleName
    Mandatory. The name of the module to be created.
 
.PARAMETER Description
    Mandatory. A short description of what the module does.
 
.PARAMETER Author
    Mandatory. The name of the author who is creating the module.
 
.PARAMETER ApiKey
    Optional. If you intend to publish the module, specify the API key here. A warning will be issued if it's left empty.
 
.EXAMPLE
    CreateModule -ModuleName "CoreePower.Dev" -Description "Library for module management" -Author "Carsten Riedel"
 
.NOTES
    This function comes with pre-configured MIT License text. Make sure it aligns with your licensing needs before publishing.
    If ApiKey is not provided, the function will proceed but will issue a warning as this is crucial for the PublishModule operation.
