-/**
- * A class that wraps an RNG and allows different String keys to be associated with biases toward low or high results
- * when a method is called that gets a number from the wrapped RNG. With this, you could make a category of "blessed" or
- * "cursed" biases that, instead of using a uniform distribution that produces all numbers approximately with equal
- * likelihood (with doubles between 0.0 and 1.0 averaging at 0.5), have different averages, like 0.7 for blessed or 0.3
- * for cursed, when generating between 0.0 and 1.0. You could also use this to favor or disfavor the player for "easy
- * mode" or "hard mode" categories of play.
- * <br>
- * The API allows you to associate an alternative average with a kind as a String, like "blessed to-hit" or "hard mode
- * enemy damage", if you expect to use that number more than once and might want to tweak any averages by changing one
- * number at a later point. You can also give an average as a double in place of a kind as a String, which avoids a
- * HashMap lookup and lets you give flexibly-adjusted numbers, but does need more effort to change many values
- * throughout a codebase if averages aren't all generated by a formula. You can also set the distribution in the
- * constructor or by changing the public distribution field; you can use constants in this class, TRIANGULAR,
- * EXPONENTIAL, TRUNCATED, SOFT_TRIANGULAR, and EXP_TRI (the average of EXPONENTIAL and TRIANGULAR), for different
- * choices, with the default being EXP_TRI. Each one of these has different behavior regarding a preference toward
- * extreme values; TRIANGULAR almost never produces very high or very low values, EXPONENTIAL frequently produces the
- * highest or lowest values for high or low expected averages, respectively, TRUNCATED will simply never generate values
- * that are too far from the average (otherwise it's uniform), SOFT_TRIANGULAR will produce a rounded version of
- * TRIANGULAR's distribution with less of an angular peak and more frequent high and low values, and EXP_TRI will have
- * something like a curve shape that may "collide" slightly with the upper bound if the average is high enough.
- * <br>
- * Credit for the technique used for the exponential modification to distributions goes to user pjs on StackOverflow,
- * http://stackoverflow.com/a/17796997 .
- * Credit should also be given to user vydd of the LispGames community, who made a visualization of the distribution
- * changing as the expected average changed (at the time, the typical behavior of an exponential distribution looked
- * like a bug, and the visualization showed that it was correct behavior). Derrick Creamer noticed how strange the
- * exponential distribution would seem to most players, and that led to adding the simple triangular distribution.
