/**
* 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 caues `$resolve` to throw an
* error. As a special case, an injectable can depend on a parameter with the same name as the injectable,
* which will be fulfilled from the `parent` injectable of the same name. This allows inherited values
* to be decorated. Note that in this case any other injectable in the same `$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.
*
* @function
* @param {Object.<string, Function|string>} invocables functions to invoke or `$injector` services to fetch.
* @param {Object.<string, *>} [locals] values to make available to the injectables
* @param {Promise.<Object>} [parent] a promise returned by another call to `$resolve`.
* @param {Object} [self] the `this` for the invoked methods

* 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 UrlMatcher#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 '}' - curly placeholder with regexp. 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.
*
* @constructor
* @param {string} pattern the pattern to compile into a matcher.
*
* @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 UrlMatcher#exec exec()} returns
* non-null) will start with this prefix.
