Local Storage with Web SQL

The WebSQL protocol can be used to work with local vector feature storage.

• navigate
• draw point
• draw line
• draw polygon
• Modify features
• Remove features using layer.removeFeatures(). They don't are removed from the storage.
• Remove features using state change and strategy.save()
• Add features
• Save the added features to local storage
• Test (to be removed!)
• Delete feature
• Clear local storage

Use the shift key to select multiple features. Use the ctrl key to toggle selection on features one at a time. Note: the "clickout" option has no effect when "hover" is selected.
