/**
* @ngdoc function
* @name ui.router.util.$resolve#resolve
* @methodOf ui.router.util.$resolve
*
* @description
* Resolves a set of invocables. An invocable is a function to be invoked via
* `$injector.invoke()`, and can have an arbitrary number of dependencies.
* An invocable can either return a value directly,
* or a `$q` promise. If a promise is returned it will be resolved and the
* resulting value will be used instead. Dependencies of invocables are resolved
* (in this order of precedence)
*
* - from the specified `locals`
* - from another invocable that is part of this `$resolve` call
* - from an invocable that is inherited from a `parent` call to `$resolve`
* (or recursively
* - from any ancestor `$resolve` of that parent).
*
* The return value of `$resolve` is a promise for an object that contains
* (in this order of precedence)
*
* - any `locals` (if specified)
* - the resolved return values of all injectables
* - any values inherited from a `parent` call to `$resolve` (if specified)
*
* The promise will resolve after the `parent` promise (if any) and all promises
* returned by injectables have been resolved. If any invocable
* (or `$injector.invoke`) throws an exception, or if a promise returned by an
* invocable is rejected, the `$resolve` promise is immediately rejected with the
* same error. A rejection of a `parent` promise (if specified) will likewise be
* propagated immediately. Once the `$resolve` promise has been rejected, no
* further invocables will be called.
*
* Cyclic dependencies between invocables are not permitted and will cause `$resolve`
* to throw an error. As a special case, an injectable can depend on a parameter
* with the same name as the injectable, which will be fulfilled from the `parent`
* injectable of the same name. This allows inherited values to be decorated.
* Note that in this case any other injectable in the same `$resolve` with the same
* dependency would see the decorated value, not the inherited value.
*
* Note that missing dependencies -- unlike cyclic dependencies -- will cause an
* (asynchronous) rejection of the `$resolve` promise rather than a (synchronous)
* exception.
*
* Invocables are invoked eagerly as soon as all dependencies are available.
* This is true even for dependencies inherited from a `parent` call to `$resolve`.
*
* As a special case, an invocable can be a string, in which case it is taken to
* be a service name to be passed to `$injector.get()`. This is supported primarily
* for backwards-compatibility with the `resolve` property of `$routeProvider`
* routes.
*
* @param {object} invocables functions to invoke or
* `$injector` services to fetch.
* @param {object} locals values to make available to the injectables
* @param {object} parent a promise returned by another call to `$resolve`.

/**
* @ngdoc object
* @name ui.router.util.type:UrlMatcher
*
* @description
* Matches URLs against patterns and extracts named parameters from the path or the search
* part of the URL. A URL pattern consists of a path pattern, optionally followed by '?' and a list
* of search parameters. Multiple search parameter names are separated by '&'. Search parameters
* do not influence whether or not a URL is matched, but their values are passed through into
* the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}.
*
* Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace
* syntax, which optionally allows a regular expression for the parameter to be specified:
*
* * `':'` name - colon placeholder
* * `'*'` name - catch-all placeholder
* * `'{' name '}'` - curly placeholder
* * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the
* regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
*
* Parameter names may contain only word characters (latin letters, digits, and underscore) and
* must be unique within the pattern (across both path and search parameters). For colon
* placeholders or curly placeholders without an explicit regexp, a path parameter matches any
* number of characters other than '/'. For catch-all placeholders the path parameter matches
* any number of characters.
*
* Examples:
*
* * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
* trailing slashes, and patterns have to match the entire path, not just a prefix.
* * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
* '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
* * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
* * `'/user/{id:[^/]*}'` - Same as the previous example.
* * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
* parameter consists of 1 to 8 hex digits.
* * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
* path into the parameter 'path'.
* * `'/files/*path'` - ditto.
* * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
* in the built-in `date` Type matches `2014-11-12`) and provides a Date object in $stateParams.start
*
* @param {string} pattern The pattern to compile into a matcher.
* @param {Object} config A configuration object hash:
* @param {Object=} parentMatcher Used to concatenate the pattern/config onto
* an existing UrlMatcher
*
* * `caseInsensitive` - `true` if URL matching should be case insensitive, otherwise `false`, the default value (for backward compatibility) is `false`.
* * `strict` - `false` if matching against a URL with a trailing slash should be treated as equivalent to a URL without a trailing slash, the default value is `true`.
*
* @property {string} prefix A static prefix of this pattern. The matcher guarantees that any
* URL matching this matcher (i.e. any string for which {@link ui.router.util.type:UrlMatcher#methods_exec exec()} returns
* non-null) will start with this prefix.
*
* @property {string} source The pattern that was passed into the constructor
*
* @property {string} sourcePath The path portion of the source property
*
* @property {string} sourceSearch The search portion of the source property
*
* @property {string} regex The constructed regex that will be used to match against the url when
* it is time to determine which url will match.
