Implementation of other API resources

[chrisspiegl]

I just noticed that the API also provides values on a daily and weekly basis. Would it be possible to implement these values into the module? That'd be great.

startdate = Start date of the historical prices
enddate = End date of the historical prices
histperiod = weekly or daily history periods 
start = index on which to display the historical price
num = number of historical prices to display (this has some max like 100 or 200)
output = output the data in a format (I think it currently supports CSV only)
