/**
* Attempts activation of plugin in a "sandbox" and redirects on success.
*
* A plugin that is already activated will not attempt to be activated again.
*
* The way it works is by setting the redirection to the error before trying to
* include the plugin file. If the plugin fails, then the redirection will not
* be overwritten with the success message. Also, the options will not be
* updated and the activation hook will not be called on plugin error.
*
* It should be noted that in no way the below code will actually prevent errors
* within the file. The code should not be used elsewhere to replicate the
* "sandbox", which uses redirection to work.
*
* If any errors are found or text is outputted, then it will be captured to
* ensure that the success redirection will update the error redirection.
*
* @since 1.0
*
* @param string $plugin Plugin path to main plugin file with plugin data.
* @param string $redirect Optional. URL to redirect to.
* @return nxt_Error|null nxt_Error on invalid file or null on success.
