    for k, v in pairs(t) do
         if type(v)=="table" then
             str = str .. propertyOffset.. k .. " = " .. printProperties(v, propertyOffset) .. ",\\n"

         end

    str = string.sub(str, 1, string.len(str) - string.len(",\\n")) .. "\\n"
    str = str .. parentOffset .. "}"
    return str
end

function printTb( tb )
