Function Resolve-PSModule

    <#
        .SYNOPSIS
        Check for a PowerShell module presence, if not there try to import/install it.

        .DESCRIPTION
        This function is not exported. The idea is to use the return searchResult from the caller function to establish
        if we can proceed to the next step where the module will be required (developed to check on Posh-SSH).
        Logic:
        - Check if module is imported into the current session
        - If module is not imported, check if available on disk and try to import
        - If module is not imported & not available on disk, try PSGallery then install and import
        - If module is not imported, not available and not in online gallery then abort

        Informing user only if the module needs importing/installing. If the module is already present nothing will be displayed.

        .EXAMPLE
        PS C:\> $poshSSH = Resolve-PSModule -moduleName "Posh-SSH"
        This example will check if the current PS module session has Posh-SSH installed, if not will try to install it
