    .SYNOPSIS
        Used to quickly search in module files.
     
    .DESCRIPTION
        This function can be used to quickly search files in your module's path.
        By using Set-PSMDModulePath (or Set-PSFConfig 'PSModuleDevelopment.Module.Path' '<path>') you can set the default path to search in.
        Using
          Register-PSFConfig -FullName 'PSModuleDevelopment.Module.Path'
        allows you to persist this setting across sessions.
     
    .PARAMETER Pattern
        The text to search for, can be any regex pattern
     
    .PARAMETER Extension
        The extension of files to consider.
        Only files with this extension will be searched.
     
    .PARAMETER Path
        The path to use as search base.
        Defaults to the path found in the setting 'PSModuleDevelopment.Module.Path'
     
    .PARAMETER EnableException
        Replaces user friendly yellow warnings with bloody red exceptions of doom!
        Use this if you want the function to throw terminating errors you want to catch.
