Update - v0.2

Made some small quality of life fixes to AtomBox:

• Added a remove object button in the properties panel. This can be used to delete previously spawned objects and particles.
• Fixed a spelling mistake in the properties panel when selecting an electric field.
• Cleaned the UI in the properties panel and made them more uniform and in-line.
• Updated the documentation.

Please let me know in the comments under this post if there are any features you would like to be added. This can include new particles or any improvements.
