/** Transformations.
* Represents two functions - from datetime (UInt32) and from date (UInt16).
*
* Also, the "factor transformation" F is defined for the T transformation.
* This is a transformation of F such that its value identifies the region of monotonicity for T
* (for a fixed value of F, the transformation T is monotonic).
*
* Or, figuratively, if T is similar to taking the remainder of division, then F is similar to division.
*
* Example: for transformation T "get the day number in the month" (2015-02-03 -> 3),
* factor-transformation F is "round to the nearest month" (2015-02-03 -> 2015-02-01).
