Exceptions

Currently JSONTools has only one type of exception, JSONToolsError. It's thrown only when you try to inserta a value into a JSON structure in a way that is impossible.

Here are some examples:

• Trying to setindex! to an object that is not a Dict or an Vector.
• Trying to setindex to a JSON data structure that has a Dict root with a path that doesn't start with a String key.
• Trying to setindex! to a JSON data structure that has a Vector root with a path that doesn't start with an Int key.
• Trying to setindex! to an array that is smaller than the index you're trying to set, without enabling the canfilllists option in the path.
• Trying to setindex! to a path that is blocked by an existing value, without enabling the candestroy option in the path.
• Trying to setindex! to a path that requires creating parent objects, without enabling the parents option in the path.
