Pull Request Checklist:

• Features and backlog bugs should be merged into the Development branch, NOT master
• Hotfixes should be merged into both the Development and master branches (at the same time).
• All new text is preferrably internationalized (i.e., no end-user-visible text is hard-coded on the PHP pages)
• There are no linter errors
• New features have responsive design (i.e., look aesthetically pleasing both full screen and with small or mobile screens)
• Symbiota coding standards have been followed
• If any files have been reformatted (e.g., by an autoformatter), the reformat is its own, separate commit in the PR
• Comment which GitHub issue(s), if any does this PR address
• It is the code author's responsibility to merge their own pull request after it has been approved
• If this PR represents a merge into the Development branch, remember to use the squash & merge option
• If this PR represents a merge from the Development branch into the master branch, remember to use the merge option
• If the dev team has agreed that this PR represents the last PR going into the Development branch before a tagged release (i.e., before an imminent merge into the master branch), make sure to notify the team and lock the Development branch to prevent accidental merges while QA takes place
