Extend arcpy.MakeFeatureLayer_management to include Group Layers

Idea created by cmcguire-esristaff Employee on Oct 7, 2015

    MakeFeatureLayer_management(in_features, out_layer, {where_clause}, {workspace}, {field_info})
    Current function requires "in_features".
    I recomend that the function be extended to take a blank "" argument for in_features and the default result be a Group Layer. I know that the means to do this is to use AddLayer and just point to an existing .lyr file on disk but when you developing scripts to send to users the dependent files can be problematic since there is more to sort out. It'd be so much simplier to let arcpy create a group layer.
    ....or make a MakeGroupLayer_management function that includes create, modify, addLayer capabilities.
