-/**

- * ChoiceFormat class.

- *

- * ChoiceFormat converts between ranges of numeric values and string

- * names for those ranges.

- *

- * A ChoiceFormat splits the real number line -Inf to +Inf into two or

- * more contiguous ranges. Each range is mapped to a string.

- * ChoiceFormat is generally used in a MessageFormat for displaying

- * grammatically correct plurals such as "There are 2 files."

- *

- * <code>

- *	$string = '[0] are no files |[1] is one file |(1,Inf] are {number} files';

- *

- *  $formatter = new MessageFormat(...); //init for a source

- *	$translated = $formatter->format($string);

- *

- *  $choice = new ChoiceFormat();

- * 	echo $choice->format($translated, 0); //shows "are no files"

- * </code>

- *

- * The message/string choices are separated by the pipe "|" followed

- * by a set notation of the form

- *  # <tt>[1,2]</tt> -- accepts values between 1 and 2, inclusive.

- *  # <tt>(1,2)</tt> -- accepts values between 1 and 2, excluding 1 and 2.

- *  # <tt>{1,2,3,4}</tt> -- only values defined in the set are accepted.

- *  # <tt>[-Inf,0)</tt> -- 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.

- *

- * Since version 3.1.2 the following set notation is also possible.

- *

- *  # <tt>{n: n % 10 > 1 && n % 10 < 5}</tt> --  matches numbers like 2, 3, 4, 22, 23, 24

- *

- * Where set is defined by the expression after <tt>n:</tt>. In particular, the expression

- * accepts the following mathematical/logical operators to form a set of logical conditions

- * on the value given by <tt>n</tt>:

- *   # <tt>&lt;</tt> -- less than.

- *   # <tt>&lt;=</tt> -- less than equals.

- *   # <tt>&gt;</tt> -- greater than.

- *   # <tt>&gt=</tt> -- greater than equals.

- *   # <tt>==</tt> -- of equal value.

- *   # <tt>%</tt> -- modulo, e.g., 1 % 10 equals 1, 11 % 10 equals 1.

- *   # <tt>-</tt> -- minus, negative.

- *   # <tt>+</tt> -- addition.

- *   # <tt>&amp;</tt> -- conditional AND.

- *   # <tt>&amp;&amp;</tt> -- condition AND with short circuit.

- *   # <tt>|</tt> -- conditional OR.

- *   # <tt>||</tt> -- conditional OR with short circuit. 

- *   # <tt>!</tt> -- negation.

- *

- * Additional round brackets can also be used to perform grouping.

- *

- * The CultureInfo class holds culture-specific information, such as the

- *

- * The culture names follow the format "<languagecode>_<country/regioncode>",

- * codes. You can find a full list of the ISO-639 codes at

- * DateFormat class.

- *

- * The DateFormat class allows you to format dates and times with

- * with the DateFormat class is similar to formatting dates.

- *

- * Formatting dates with the DateFormat class is a two-step process.

- * First, you create a formatter with the getDateInstance method.

- * Second, you invoke the format method, which returns a string containing

- * the formatted date.

- *

- * DateTime values are formatted using standard or custom patterns stored

- * </code>

- * you may pass a CultureInfo parameter $culture to get the DateTimeFormatInfo

- * DateTime values are formatted using standard or custom patterns stored in

- *

- * The standard patterns can be replaced with custom patterns by setting the

- * The following table lists the standard format characters for each standard

- * A custom message source can be instantiated by specifying the filename

- * set the cache handler, and use the source in a message formatter. 

- * The messages are stored using an existing connection. The source parameter

- * <code>

-/**

- * NumberFormat class.

- *

- * NumberFormat formats decimal numbers in any locale. The decimal

- * number is formatted according to a particular pattern. These

- * patterns can arise from the NumberFormatInfo object which is

- * culturally sensitive. The NumberFormat class can be instantiated in

- * many ways. E.g.

- *

- * <code>

- *  //create a invariant number formatter.

- *	$formatter = new NumberFormat();

- *

- *  //create a number format for the french language locale.

- *  $fr = new NumberFormat('fr');

- *

- *  //create a number format base on a NumberFormatInfo instance $numberInfo.

- *  $format = new NumberFormat($numberInfo);

- * </code>

- *

- * A normal decimal number can also be displayed as a currency

- * or as a percentage. For example

- * <code>

- * $format->format(1234.5); //Decimal number "1234.5"

- * $format->format(1234.5,'c'); //Default currency "$1234.50"

- * $format->format(0.25, 'p') //Percent "25%"

- * </code>

- *

- * Currency is formated using the localized currency pattern. For example

- * to format the number as Japanese Yen:

- * <code>

- *  $ja = new NumberFormat('ja_JP');

- *

- *  //Japanese currency pattern, and using Japanese Yen symbol

- *  $ja->format(123.14,'c','JPY'); //�?123 (Yen 123)

- * </code>

- * For each culture, the symbol for each currency may be different.

-* Fast, light and safe Cache Class

-*

-* TCache_Lite is a fast, light and safe cache system. It's optimized

-* for file containers. It is fast and safe (because it uses file

-* locking and/or anti-corruption tests).

-*

-* There are some examples in the 'docs/examples' file

-* Technical choices are described in the 'docs/technical' file

-*

-* A tutorial is available in english at this url :

-* http://www.pearfr.org/index.php/en/article/cache_lite

-* (big thanks to Pierre-Alain Joye for the translation)

-*

-* The same tutorial is also available in french at this url :

-* http://www.pearfr.org/index.php/fr/article/cache_lite

-* Memory Caching is from an original idea of
