.Synopsis
    Create a chocolatey package
.Description
    Used to create a packed chocolatey package with a standard folder structure consiting of:
    |--Tools
    | |-chocolateyinstall.ps1
    | |-<installer>.(msi,exe,mst)
    |--<name><version>.nupkg
    |--<name>.nuspec
    |--Readme
.Example
    Example goes here
.Parameter Name
    The name of the package. Cannot contain spaces. Avoid special characters.
    Mandatory
.Parameter Version
    The software version in major.minor.build format i.e 1.0.0.
    Mandatory and must be in the prevouisly stated format
.Parameter Path
    The path to the installer. This can be a local file path, a file share path or a URL. It will depend on your end goal.
    If you are developing and testing, this will most liekly be a local path. If you plan to publish this package straight to your
    Chocolatey source, use the file path to the installer that is accesible to your end users.
    Mandatory
.Parameter Type
    The type of installer. ex. .exe, .msi or .mst. It sets the type based on path passed to the "Path" parameter.
    If the installer is an .msi, the generic flags "/q /norestart" will be automatically added.
    Otherwise, you will be prompteed for the .exe or .mst silent arguments. (Which is when Test-ChocolateyPackage comes in handy
    because you don't want to be install and uninstalling software on your machine just to test)
    Automatic
.Parameter Template
    The template decides if the .msi, .exe or .mct will be stored within the .nupkg.
    The Embedded Template stores it in the tools file along with the chocolateyinstall.ps1
    The External Template expects the final location of the installer to be provided.
    It is best to embbed, unless the installer is over 100MB.
.Parameter Maintainer
    The creator/maintainer of the package. Set to "Author" if no value is provided
    Optional
