#### `craftguide.progressive_filter_recipes(recipes, player)`
This function is used to filter recipes when progressive mode is enabled. It can
be overridden to change the recipes that are normally displayed.
The function should return the recipes to be displayed, given the available
recipes and an `ObjectRef` to the craft guide user. Each recipe is a table of
the form returned by `minetest.get_craft_recipe`.
Example function to hide recipes for items from a mod called "secretstuff":
```lua
function craftguide.progressive_filter_recipes(recipes, player)
local filtered = {}
for _, recipe in ipairs(recipes) do
if recipe.output:sub(1, 12) ~= "secretstuff:" then
filtered[#filtered + 1] = recipe
end
end
return filtered
end
```
