Tracking issue to make sure the metatile system is documented.

We discuss in the discord server about the benefits of an option that allows a priority of selection tool over the layers (kind of similar to photoshop or others semi-advanced raster editors)

This is nothing against Leaflet, which remains as awesome as ever.

However, for easier maintenance and enhancements, it would be best to limit our map preview technology to a single type.

Serin's comment on #159:

When loading the options file, a label at the bottom has text set to a file path. If the path is long, the whole window expands to allow it to be displayed. The effect is quite jarring, and very long paths could cause problems, so I think the path should be cut off, or the label should have multiple lines.

Things to do:

• Correct typos
• Sort methods
• Delete unused functions
• Complete documentation
• Correct documentation
• Improve comments
• Rename methods, variables and classes to more sense

I noticed the doc folder is gone. Not sure if that was intentional or not, but I think the project could benefit from some basic documentation. You should also include documentation for what properties a object/layer/map table contains. This will be useful for when people are creating (whatever kind of) objects to look at a table they can reference.
