/**
 * Searches and matches file paths using Ant-like globs.
 *
 * This class implements an Ant-like version of PHP's `glob()` function. The
 * wildcard "*" matches any number of characters except directory separators.
 * The double wildcard "**" matches any number of characters, including
 * directory separators.
 *
 * Use {@link glob()} to glob the filesystem for paths:
 *
 * ```php
 * foreach (Glob::glob('/project/**.twig') as $path) {
 *     // do something...
 * }
 * ```
 *
 * Use {@link match()} to match a file path against a glob:
 *
 * ```php
 * if (Glob::match('/project/views/index.html.twig', '/project/**.twig')) {
 *     // path matches
 * }
 * ```
 *
 * You can also filter an array of paths for all paths that match your glob with
 * {@link filter()}:
 *
 * ```php
 * $filteredPaths = Glob::filter($paths, '/project/**.twig');
 * ```
 *
 * Internally, the methods described above convert the glob into a regular
 * expression that is then matched against the matched paths. If you need to
 * match many paths against the same glob, you should convert the glob manually
 * and use {@link preg_match()} to test the paths:
 *
 * ```php
 * $staticPrefix = Glob::getStaticPrefix('/project/**.twig');
 * $regEx = Glob::toRegEx('/project/**.twig');
 *
 * if (0 !== strpos($path, $staticPrefix)) {
 *     // no match
 * }
 *
 * if (!preg_match($regEx, $path)) {
 *     // no match
 * }
 * ```
 *
 * The method {@link getStaticPrefix()} returns the part of the glob up to the
 * first wildcard "*". You should always test whether a path has this prefix
 * before calling the much more expensive {@link preg_match()}.
 *

19			* Searches and matches file paths using Ant-like globs.
20			*
21			* This class implements an Ant-like version of PHP's `glob()` function. The
22			* wildcard "*" matches any number of characters except directory separators.
23			* The double wildcard "**" matches any number of characters, including
24			* directory separators.
25			*
26			* Use {@link glob()} to glob the filesystem for paths:
27			*
28			* ```php
29			* foreach (Glob::glob('/project/**.twig') as $path) {
30			* // do something...
31			* }
32			* ```
33			*
34			* Use {@link match()} to match a file path against a glob:
35			*
36			* ```php
37			* if (Glob::match('/project/views/index.html.twig', '/project/**.twig')) {
38			* // path matches
39			* }
40			* ```
41			*
42			* You can also filter an array of paths for all paths that match your glob with
43			* {@link filter()}:
44			*
45			* ```php
46			* $filteredPaths = Glob::filter($paths, '/project/**.twig');
47			* ```
48			*
49			* Internally, the methods described above convert the glob into a regular
50			* expression that is then matched against the matched paths. If you need to
51			* match many paths against the same glob, you should convert the glob manually
52			* and use {@link preg_match()} to test the paths:
53			*
54			* ```php
55			* $staticPrefix = Glob::getStaticPrefix('/project/**.twig');
56			* $regEx = Glob::toRegEx('/project/**.twig');
57			*
58			* if (0 !== strpos($path, $staticPrefix)) {
59			* // no match
60			* }
61			*
62			* if (!preg_match($regEx, $path)) {
63			* // no match
64			* }
65			* ```
66			*
67			* The method {@link getStaticPrefix()} returns the part of the glob up to the
68			* first wildcard "*". You should always test whether a path has this prefix
69			* before calling the much more expensive {@link preg_match()}.
70			*
