"""
Contains some faster coordinate transformations than the ones currently used in astropy.

This is based on an idea put forward by @bwinkel in the pull request located at
at https://github.com/astropy/astropy/pull/6068. This may be merged into the astropy
master at some point. If this happens, this module can be removed.

Simply import into code to experience the speedups; the astropy coordinate transforms are
overwritten on modeul import.

// In order to use the script, you must create a Slack app and install it on your workspace. Go here to create your app: api.slack.com/apps
// There's two important configurations you must make to the app:
// 1. Add the users.profile:write scope to the app. This scope is necessary to set a Slack status.
// 2. Add the following redirect URL, so Slack will redirect to Scriptable after authorizing.
// https://open.scriptable.app

// Run the script to grant your newly created app authorization to access your Slack account. After you've done this, you can use the script in Shortcuts.

THE USE OF SUB-ROUTINES IN PROGRAMMES

D. J. Wheeler

Cambridge & Illinois Universities

A sub-routine may perhaps best be described as a self-contained part of a programme, which is capable of being used in different programmes. It is an entity of its own within a programme. There is no necessity to compose a programme of a set of distinct sub-routines; for the programme can be written as a complete unit, with no divisions into smaller parts. However it is usually advantageous to arrange that a programme is comprised of a set of subroutines, some of which have been made specially for the particular programme while others are available from a library of standard sub-routines. The reasons for this will be discussed below.

When a programme has been made from a set of sub-routines the breakdown of the code is more complete than it would otherwise be. This allows the coder to concentrate on one section of a programme at a time without the overall detai
