This transforms the XML returned by gCal's API into something more readable (PHP arrays). Features include:

• merges multiple calendars onto one schedule
• grabs the nearest up and coming event for recurring events (takes exceptions into account)
• allows pseudo-tagging (categorizing, to be more accurate)
• enables marking an event as normal, important, or very important
• automatically parses location name ('Unit 3') and physical address ('2400 Durant Ave, Berkeley CA')
