Beatmap Format

I've tweaked the format since SIF Train into something more simple.

Sample:

{ "metadata":{ "songName":"TUTORIAL", "songFile":"song_0", "composer":"TUTORIAL", "lyricist":"TUTORIAL", "id":0, "difficultyName":"Debut", "difficulty":0, "attribute":0, "bpm":60, "duration":9.6}, "notes":[ { "id":1, "timing":0.6, "type":1, "startPos":3, "endPos":3, "status":0, "sync":0, "groupId":0, "nextNoteId":0, "prevNoteId":0 }, { "id":2, "timing":1.8, "type":1, "startPos":3, "endPos":3, "status":0, "sync":0, "groupId":0, "nextNoteId":0, "prevNoteId":0 }, { "id":3, "timing":3.0, "type":1, "startPos":3, "endPos":3, "status":0, "sync":0, "groupId":0, "nextNoteId":0, "prevNoteId":0 }, { "id":4, "timing":4.2, "type":1, "startPos":3, "endPos":3, "status":0, "sync":0, "groupId":0, "nextNoteId":0, "prevNoteId":0 }, { "id":5, "timing":5.4, "type":1, "startPos":3, "endPos":3, "status":0, "sync":0, "groupId":0, "nextNoteId":0, "prevNoteId":0 }, { "id":6, "timing":6.6, "type":1, "startPos":3, "endPos":3, "status":0, "sync":0, "groupId":0, "nextNoteId":0, "prevNoteId":0 }]
