/**
* TChoiceFormat class.
*
* This component performs message/string choice translation. The translation
* source is set in the TGlobalization module. The following example
* demonstrates a simple 2 choice message translation.
*
* [1] One Apple. |[2] Two Apples
*
*
* The Choice has Value "1" (one), thus the translated string
* is "One Apple". If the Value is "2", then it will show
* "Two Apples".
*
* The message/string choices are separated by the pipe "|" followed
* by a set notation of the form
* # [1,2] -- accepts values between 1 and 2, inclusive.
* # (1,2) -- accepts values between 1 and 2, excluding 1 and 2.
* # {1,2,3,4} -- only values defined in the set are accepted.
* # [-Inf,0) -- accepts value greater or equal to negative infinity
* and strictly less than 0
* Any non-empty combinations of the delimiters of square and round brackets
* are acceptable.
*
* The string choosen for display depends on the Value property.
* The Value is evaluated for each set until the Value is found
* to belong to a particular set.
*
* Properties
* - Value, float,
*
Gets or sets the Value that determines which string choice to display.
* Since version 3.1.2 the following set notation is also possible.
*
* # {n: n % 10 > 1 && n % 10 < 5} -- matches numbers like 2, 3, 4, 22, 23, 24
*
* Where set is defined by the expression after n:. In particular, the expression
* accepts the following mathematical/logical operators to form a set of logical conditions
* on the value given by n:
* # < -- less than.
* # <= -- less than equals.
* # > -- greater than.
* # >= -- greater than equals.
* # == -- of equal value.
* # % -- modulo, e.g., 1 % 10 equals 1, 11 % 10 equals 1.
* # - -- minus, negative.
* # + -- addition.
* # & -- conditional AND.
* # && -- condition AND with short circuit.
* # | -- conditional OR.
* # || -- conditional OR with short circuit.
* # ! -- negation.
*
* Additional round brackets can also be used to perform grouping.
