* Package Configuration Extension
*
* Example:
*
* SystemJS.packages = {
* jquery: {
* main: 'index.js', // when not set, package name is requested directly
* format: 'amd',
* defaultExtension: 'ts', // defaults to 'js', can be set to false
* modules: {
* '*.ts': {
* loader: 'typescript'
* },
* 'vendor/sizzle.js': {
* format: 'global'
* }
* },
* map: {
* // map internal require('sizzle') to local require('./vendor/sizzle')
* sizzle: './vendor/sizzle.js',
* // map any internal or external require of 'jquery/vendor/another' to 'another/index.js'
* './vendor/another.js': './another/index.js',
* // test.js / test -> lib/test.js
* './test.js': './lib/test.js',
*
* // environment-specific map configurations
* './index.js': {
* '~browser': './index-node.js'
* }
* },
* // allows for setting package-prefixed depCache
* // keys are normalized module names relative to the package itself
* depCache: {
* // import 'package/index.js' loads in parallel package/lib/test.js,package/vendor/sizzle.js
* './index.js': ['./test'],
* './test.js': ['external-dep'],
* 'external-dep/path.js': ['./another.js']
* }
* }
* };
*
* Then:
* import 'jquery' -> jquery/index.js
* import 'jquery/submodule' -> jquery/submodule.js
* import 'jquery/submodule.ts' -> jquery/submodule.ts loaded as typescript
* import 'jquery/vendor/another' -> another/index.js
*
* Detailed Behaviours
* - main can have a leading "./" can be added optionally
* - map and defaultExtension are applied to the main
* - defaultExtension adds the extension only if the exact extension is not present
* - defaultJSExtensions applies after map when defaultExtension is not set
* - if a meta value is available for a module, map and defaultExtension are skipped
* - like global map, package map also applies to subpaths (sizzle/x, ./vendor/another/sub)
* - condition module map is '@env' module in package or '@system-env' globally
* - map targets support conditional interpolation ('./x': './x.#{|env}.js')
* - internal package map targets cannot use boolean conditionals
*
* Package Configuration Loading
*
* Not all packages may already have their configuration present in the System config
* For these cases, a list of packageConfigPaths can be provided, which when matched against
* a request, will first request a ".json" file by the package name to derive the package
* configuration from. This allows dynamic loading of non-predetermined code, a key use
* case in SystemJS.
*
* Example:
*
* SystemJS.packageConfigPaths = ['packages/test/package.json', 'packages/*.json'];
*
* // will first request 'packages/new-package/package.json' for the package config
* // before completing the package request to 'packages/new-package/path'
* SystemJS.import('packages/new-package/path');
*
* // will first request 'packages/test/package.json' before the main
* SystemJS.import('packages/test');
*
* When a package matches packageConfigPaths, it will always send a config request for
* the package configuration.
* The package name itself is taken to be the match up to and including the last wildcard
* or trailing slash.
* The most specific package config path will be used.
* Any existing package configurations for the package will deeply merge with the
* package config, with the existing package configurations taking preference.
* To opt-out of the package configuration request for a package that matches
* packageConfigPaths, use the { configured: true } package config option.
*

* Instantiate registry extension

* - Also supports metadata.deps, metadata.execute and metadata.executingRequire
* for handling dynamic modules alongside register-transformed ES6 modules
*
*
* The code here replicates the ES6 linking groups algorithm to ensure that

* Registry Entry Contains:
* - name

* - executingRequire indicates require drives execution for circularity of dynamic modules
* - declarative optional boolean indicating which of the above
*
* Can preload modules directly on SystemJS.defined['my/module'] = { deps, execute, executingRequire }
*
* Then the entry gets populated with derived information during processing:
* - normalizedDeps derived from deps, created in instantiate
* - groupIndex used by group linking algorithm
* - evaluated indicating whether evaluation has happend
* - module the module record object, containing:
* - exports actual module exports
*
* For dynamic we track the es module with:
* - esModule actual es module value
* - esmExports whether to extend the esModule with named exports
*
* Then for declarative only we track dynamic bindings with the 'module' records:
* - name
* - exports
* - setters declarative setter functions
* - dependencies, module records of dependencies
* - importers, module records of dependents
*
* After linked and evaluated, entries are removed, declarative module records remain in separate

* Conditions Extension
*
* Allows a condition module to alter the resolution of an import via syntax:
*
* import $ from 'jquery/#{browser}';
*
* Will first load the module 'browser' via `SystemJS.import('browser')` and
* take the default export of that module.
* If the default export is not a string, an error is thrown.
*
* We then substitute the string into the require to get the conditional resolution
* enabling environment-specific variations like:
*
* import $ from 'jquery/ie'
* import $ from 'jquery/firefox'
* import $ from 'jquery/chrome'
* import $ from 'jquery/safari'
*
* It can be useful for a condition module to define multiple conditions.
* This can be done via the `|` modifier to specify an export member expression:
*
* import 'jquery/#{./browser.js|grade.version}'
*
* Where the `grade` export `version` member in the `browser.js` module is substituted.
*
*
* Boolean Conditionals
*
* For polyfill modules, that are used as imports but have no module value,
* a binary conditional allows a module not to be loaded at all if not needed:
*
* import 'es5-shim#?./conditions.js|needs-es5shim'
*
* These conditions can also be negated via:
*
* import 'es5-shim#?~./conditions.js|es6'
*

*
* my/module.js
* "format amd";
* "deps[] jquery";
* "globals.some value"
* console.log('this is my/module');
*
* Configuration meta always takes preference to inline meta.
*
* Multiple matches in wildcards are supported and ammend the meta.
*
*
* The benefits of the function form is that paths are URL-normalized
* supporting say
*
* loader.meta({ './app': { format: 'cjs' } });
*
* Instead of needing to set against the absolute URL (https://site.com/app.js)
