[V3] Analyzer extension for concept exercise: basic-slices

[tehsphinx]

This issue describes what the Go analyzer should check for in the card-tricks exercise.

Function GetItem

• no else should be used
• early return should be used which makes a total sum of 2 return statements.
• there needs to be exactly one if statement (with 2 conditions)
• no switch should be used

Function SetItem

• all 4 checks of GetItem apply here as well

Function PrefilledSlice

• check instantiation of the slice. It should be created with a len or cap given
• check for a for loop (no range, not recursive)

Function NumberRow

• check instantiation of the slice. No make or new should be used but a nil slice created with var xy []int
• optional: check if for loop increases index (for i := 1; true; i++)

Function RemoveItemPure

• all 4 checks of GetItem apply here as well
• shouldn't use a for loop, only append

Function RemoveItem

• all 4 checks of GetItem apply here as well
