/**
 * This plugin is currently a A Big Hack™! The core reason for that is how this plugin
 * interacts with Uppy's current pipeline design. The pipeline can handle files in steps,
 * including preprocessing, uploading, and postprocessing steps. This plugin initially
 * was designed to do its work in a preprocessing step, and let XHRUpload deal with the
 * actual file upload as an uploading step. However, Uppy runs steps on all files at once,
 * sequentially: first, all files go through a preprocessing step, then, once they are all
 * done, they go through the uploading step.
 *
 * For S3, this causes severely broken behaviour when users upload many files. The
 * preprocessing step will request S3 upload URLs that are valid for a short time only,
 * but it has to do this for _all_ files, which can take a long time if there are hundreds
 * or even thousands of files. By the time the uploader step starts, the first URLs may
 * already have expired. If not, the uploading might take such a long time that later URLs
 * will expire before some files can be uploaded.
 *
 * The long-term solution to this problem is to change the upload pipeline so that files
 * can be sent to the next step individually. That requires a breaking change, so it is
 * planned for some future Uppy version.
 *
 * In the mean time, this plugin is stuck with a hackier approach: the necessary parts
 * of the XHRUpload implementation were copied into this plugin, as the MiniXHRUpload
 * class, and this plugin calls into it immediately once it receives an upload URL.
 * This isn't as nicely modular as we'd like and requires us to maintain two copies of
 * the XHRUpload code, but at least it's not horrifically broken :)

/**
 * Creates a throttled function that only invokes `func` at most once per
 * every `wait` milliseconds. The throttled function comes with a `cancel`
 * method to cancel delayed `func` invocations and a `flush` method to
 * immediately invoke them. Provide `options` to indicate whether `func`
 * should be invoked on the leading and/or trailing edge of the `wait`
 * timeout. The `func` is invoked with the last arguments provided to the
 * throttled function. Subsequent calls to the throttled function return the
 * result of the last `func` invocation.
 *
 * **Note:** If `leading` and `trailing` options are `true`, `func` is
 * invoked on the trailing edge of the timeout only if the throttled function
 * is invoked more than once during the `wait` timeout.
 *
 * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
 * until to the next tick, similar to `setTimeout` with a timeout of `0`.
 *
 * See [David Corbacho's article](https://css-tricks.com/debouncing-throttling-explained-examples/)
 * for details over the differences between `_.throttle` and `_.debounce`.

  # wildcard

  Very simple wildcard matching, which is designed to provide the same
  functionality that is found in the
  [eve](https://github.com/adobe-webplatform/eve) eventing library.

  ## Usage

  It works with strings:

  <<< examples/strings.js

  Arrays:

  <<< examples/arrays.js

  Objects (matching against keys):

  <<< examples/objects.js

  While the library works in Node, if you are are looking for file-based
  wildcard matching then you should have a look at:
