    .EXAMPLE
        # Create a vector out of two numbers
        Vector3 1 2 3
    .EXAMPLE
        (Vector3 1 2 3 ) + (Vector3 3 2 1)
    .EXAMPLE
        (Vector3 1 2 3 ) - (Vector3 3 2 1)
    .EXAMPLE
        # Create a thousand vectors
        $vectors = Vector3 1..3kb
    .EXAMPLE
        # Create a thousand vectors in random order, using the pipeline
        $vectors = 1..3kb | Get-Random -Count 3kb | Vector3
    .EXAMPLE
        # Create a vector from a string
        $vector = Vector3 "hi"
