Summary: These are utility function for reading from the IndexedDB and writing to it. This will be used for persistant storage of bookmarks. The reason I chose IndexedDB over local storage is due to the poor efficiency of stringifying and parsing a long list of bookmarks everytime we read and write to local storage. With IndexedDB we can modify a single value at a time. Bookmarks are passed around as a Map, with the key being the uri's and the common names being the values. This allows me to check if a specified uri is in the Map in O(1) time, so that I can highlight the star icon in the UI with gold.
