// TODO: only allow specific amount of cards to be active at one time. this hsould of course also adjust based on the user.
//       Maybe check the ratio of consecutiveCorrect new Cards. if all new cards have a 'positive ratio', than new cards are accepable,
//       since the user is doing well on consective tests. if consectuvie correct has a bad ratio across all new words, focus on repetition of new words.
//       pseudo: var amountOFNewCardsPossible =  count(newCards).with('consecutive correct > 3') / count(newCards).with('totalwrong' > 3)
//       should result in a number of newCards and if new Cards are being still introduced.

//TODO: Premature review: New interval should be: (last review + days since) * easinessfactor , Easinessfactor should be increased by root distance to target reviewDate ie. if target review was 10Days, but has been reviewed prematurely after 1 day. Distance = (1/10)**2
// Easiness = easiness + (FormulaResult) * Distance

Glossary:
New Card/Word: A word that has been newly introduced and is not yet matured. The unit for the interval timer is minutes.

Mature Card/Word: A card that has been correctly answered {newWordCutoff} many times, and is no longer a "New Card". This changes the Interval unit to days instead of minutes.
