The implementation of processing load/mutation result graph targeting.

The algorithm and support functions for converting a normalized Fulcro database to a tree of denormalized props.

Some misc. utility functions. These are primarily meant for internal use, and are subject to
relocation and removal in the future.

You have been warned. Changes to this ns (or its complete removal)
will not be considered breaking changes to the library, and no mention of said changes
will even appear in the changelog.

Functions that assist with supporting form editing/checking/diffing in Fulcro UI.  These functions work
by making a pristine copy of your entity, and tracking what fields have been touched.  You are responsible
for triggering these various states by marking fields as complete (`mark-complete!`), telling it to
copy the data to/from pristine (e.g. `entity->pristine`), and by asking for out-of-date data for the current
vs. pristine copy (`dirty-fields`).

There is also support for detecting which fields have been marked complete and are dirty.

Validation can be done via Clojure spec (not recommended), or by defining your own field validation functions via
`make-validator` (recommended). This general-purpose validation factory function can easily be used to create more
automated validation factories that can be more configuration-driven, but this is left as an exercise for the community.

Specs are not recommended because forms commonly have multi-field dependencies that simply are
not well-supported, and sometimes the use of things like Fulcro tempids leads to specs that you'd
rather not have on your server. Use of spec really boils down to your intention for those
spec (i.e. hard validation of final database value vs. potential runtime look of the data as
it is manipulated). Specs that include "state" information will cause you more pain than
you want, though you can certainly leverage specs anywhere it makes sense using the validator factory.

IMPORTANT: This namespace is about *(possibly recursive) form data management*. Rendering and
such are not part of the stated intention. See Fulcro RAD for more fully-automated,
multi-platform form generation.

See the Developer's Guide for more information.

Functions that implement the query and component indexing. Fulcro keeps indexes of on-screen
components by ident and class. These enable Fulcro to find on-screen components for things
like targeted refresh. You are allowed to use the indexes to find components for whatever
purpose suits your needs (e.g. looking at component options).

Fulcro is quite customizable, and all of the pluggable algorithms are stored on the app. This
very easily leads to a desire to alias the long com.fulcrologic.fulcro.application namespace
to something like `app` for easy access to keyword aliasing, but in Clojure this leads
to circular references. This namespace exists simply to save typing and hassle with
respect to that. It includes `app-algorithm` which can look up a plug-in algorithm on
an app using a simple keyword without having to require the application ns.

Various algorithms that are used for merging trees of data into a normalized Fulcro database.

Functions for dealing with normalizing Fulcro databases. In particular `tree->db`.

Functions that can be used against a normalized Fulcro state database. This namespace also includes some handy aliases
to useful functions that work on normalized state from other namespaces.

Algorithms for delaying some action by a particular amount of time.

Functions for making and consuming Fulcro temporary IDs. Tempids are used when the client is optimistically
creating a new entity and you want to be able to detect that on the server when the data is sent. Additionally,
Fulcro mutations can return a remapping instruction from the server to rewrite all tempids in the client
(state, network queues, etc.) atomically.

This allows the client to safely generate new entities with a temporary ID and let the server remap them to the real
IDs at some future time.  Transit read/write is included, so that (de)serialization of them can be consistent whenever
needed (see the `transit` ns in this package).

(ns app.development-preload
  (:require
    [taoensso.timbre :as log]
    [com.fulcrologic.fulcro.algorithms.timbre-support :refer [console-appender prefix-output-fn]))

(log/set-level! :debug)
(log/merge-config! {:output-fn prefix-output-fn
                    :appenders {:console (console-appender)}})

(try
  ...
  (catch :default ex
    (log/error ex ...))

Logging helpers to make js console logging more readable. The recommended use of these functions is as follows:

- Make sure you're using Binaryage devtools (on classpath. shadow-cljs will auto-add it when detected).
- IMPORTANT: Enable custom formatters in console settings for Chrome. This will print cljs data as cljs (instead of raw js).
- Make a development preload cljs file, and tell shadow-cljs to preload it.
- In the preload file, add something like this:

```
(ns app.development-preload
  (:require
    [taoensso.timbre :as log]
    [com.fulcrologic.fulcro.algorithms.timbre-support :refer [console-appender prefix-output-fn]))

(log/set-level! :debug)
(log/merge-config! {:output-fn prefix-output-fn
                    :appenders {:console (console-appender)}})
```

and you'll get much more readable error messages in the js console.

NOTE: when logging errors, be sure to log the exception first. This is documented in timbre, but easy to miss:

```
(try
  ...
  (catch :default ex
    (log/error ex ...))
```

See the development_preload.cljs and shadow-cljs.edn files in the latest Fulcro 3 template for an example.

Transit functions for the on-the-wire EDN communication to common remotes. Includes support for Fulcro tempids,
and can be extended to support additional application-specific data types.

The transaction processing in Fulcro is (intended to be) pluggable. This namespace is the
implementation for the default transaction processing . At the present time there is no documentation on how
such an override would be written, nor is it necessarily recommended since many of the desirable and built-in
behaviors of Fulcro are codified here. 

Helper functions for debugging tx processing.  Uses pprint, which adds
a lot to build size, so it is in a separate ns to keep it out of prod builds.
