//A single step's points are calculated as follows:
//
//Let p = score multiplier (Perfect = 10, Great = 5, other = 0)
//N = total number of steps and freeze steps
//n = number of the current step or freeze step (varies from 1 to N)
//B = Base value of the song (1,000,000 X the number of feet difficulty) - All edit data is rated as 5 feet
//So, the score for one step is:
//one_step_score = p * (B/S) * n
//Where S = The sum of all integers from 1 to N (the total number of steps/freeze steps)
//
//*IMPORTANT* : Double steps (U+L, D+R, etc.) count as two steps instead of one, so if you get a double L+R on the 112th step of a song, you score is calculated with a Perfect/Great/whatever for both the 112th and 113th steps. Got it? Now, through simple algebraic manipulation
//S = 1+...+N = (1+N)*N/2 (1 through N added together)
//Okay, time for an example:
//
//So, for example, suppose we wanted to calculate the step score of a "Great" on the 57th step of a 441 step, 8-foot difficulty song (I'm just making this one up):
//
//S = (1 + 441)*441 / 2
//= 194,222 / 2
//= 97,461
//StepScore = p * (B/S) * n
//= 5 * (8,000,000 / 97,461) * 57
//= 5 * (82) * 57 (The 82 is rounded down from 82.08411...)
//= 23,370
//Remember this is just the score for the step, not the cumulative score up to the 57th step. Also, please note that I am currently checking into rounding errors with the system and if there are any, how they are resolved in the system.
//
//Note: if you got all Perfect on this song, you would get (p=10)*B, which is 80,000,000. In fact, the maximum possible score for any song is the number of feet difficulty X 10,000,000.
