    <#
    .SYNOPSIS
        Creates a new credential store File

    .DESCRIPTION
        You need to run this script first to create a new credential store before you try to
        save new credentials with New-CredentialStoreItem.

    .PARAMETER Path
        Define a location for the new shared CredentialStore. The default store will be created in
        $Env:ProgramData\PSCredentialStore dir.

    .PARAMETER Shared
        Creates a CredentialStore in the Shared mode. This enables you to read the CredentialStore Items on
        different systems or profiles. In addition you can optionally provide a custom path wit the -Path parameter.

    .PARAMETER Force
        Use this switch to reset an existing store. The complete content will be wiped.

    .INPUTS
        [None]

    .OUTPUTS
        [None]

    .EXAMPLE
        New-CredentialStore
        # Creates a new private CredentialStore

    .EXAMPLE
        New-CredentialStore -Force
        # Resets an existing private CredentialStore

    .EXAMPLE
        New-CredentialStore -Shared
        # Creates a new shared CredentialStore

    .EXAMPLE
        New-CredentialStore -Shared -Path "C:\TMP\CredentialStore.json"
        # Creates a new shared CredentialStore in the given location.
