LTI Tool Provider Library PHP
=============================

Some changes from the upstream version have been made:
* Define consumer profile member variable for ToolConsumer class
* Added context type property for Context class
* Set context type if 'context_type' parameter was submitted through POST
* Do not require tool_consumer_instance_guid
* Prevent modification of the request to the provider
These changes can be reverted once the following pull requests have been integrated upstream:
* https://github.com/1EdTech/LTI-Tool-Provider-Library-PHP/pull/10
* https://github.com/1EdTech/LTI-Tool-Provider-Library-PHP/pull/11
* https://github.com/1EdTech/LTI-Tool-Provider-Library-PHP/pull/47
* https://github.com/1EdTech/LTI-Tool-Provider-Library-PHP/pull/48

This local changes can be reverted once it's checked that they are present upstream (note the
LTI-Tool-Provider-Library-PHP repo has been archived so it doesn't accept pull requests anymore):
* MDL-67034 php74 compliance fixes
* MDL-71920: Migrated from curl_exec and friends to use our Moodle curl wrapper,
so we can better handle site security settings

This local change has been made without the accompanying pull request as the upstream library is archived:
* $FULLME is used as the URL for OAuth, to fix reverse proxy support (see MDL-64152)

It is recommended by upstream to install depdencies via composer - but the composer installation is bundled
with an autoloader so it's better to do it manually.
