VERY WIP (I'll move it to the main namespace if it's finished.)

The letter comma notation (LCN) is a notation scheme developed by CompactStar for just intonation up to the 31-limit as well as regular temperaments based on it. As with other JI notations, it is based on 3-limit notation with a set of accidentals corresponding to a formal comma for each prime limit. The letters H-Z are used for these accidentals, and alternate between ascending and descending, so H is 5-limit ascending, I is 5-limit descending, J is 7-limit ascending, K is 7-limit descending and so on. This notation bears similarity to FJS but it aims to be more easily typable.
