Nasty.Translation.Agreement (Nasty v0.3.0)

Enforces grammatical agreement in target language.

Different languages require agreement between words:

Gender agreement: adjectives, articles, determiners agree with nouns (Spanish, Catalan)
Number agreement: verbs agree with subjects, adjectives with nouns
Person agreement: verb conjugation matches subject person

English has minimal agreement (only number and person for verbs), while Romance languages have extensive agreement.
