Looking at the creation of the instances of pyparse.PyParse() and hyperparser.HyperParser(), I was a little surprised that they (the instances) are local variables to the methods and aren't instance variables.  Since they are called fairly often, wouldn't it be more efficient to use an instance variable (for example self.hp in calltips instead of hp) and update the attributes when something like open_calltips() is executed?  Maybe the overhead of creating a class is neglible compared to the storage of not destroying it every time?
