function New-DynamicModuleBuilder {
    <#
    .SYNOPSIS
        Creates a new assembly and a dynamic module within the current AppDomain.
    .DESCRIPTION
        Prepares a System.Reflection.Emit.ModuleBuilder class to allow construction of dynamic types. The ModuleBuilder is created to allow the creation of multiple types under a single assembly.
