        .SYNOPSIS
        Resolve dependencies for a module based on the manifest file.

        .DESCRIPTION

        .EXAMPLE
        Resolve-PSModuleDependency -Path 'C:\MyModule\MyModule.psd1'

        Installs all modules defined in the manifest file, following PSModuleInfo structure.

        Should later be adapted to support both pre-reqs, and dependencies.
        Should later be adapted to take 4 parameters sets: specific version ("requiredVersion" | "GUID"), latest version ModuleVersion,
        and latest version within a range MinimumVersion - MaximumVersion.
