Read data from Yahoo for multiple assets

A poorly implemented function to get a specific type of data from Yahoo for a number of assets.

pp.TTR.multsymbol(symbols, start, end, item = "Close", 
	adjust = TRUE, verbose = TRUE)

`symbols`	a character vector giving the symbols of the assets of interest.
`start`	an integer in the form of yyyymmdd giving the starting date.
`end`	an integer in the form of yyyymmdd giving the ending date.
`item`	a string giving the data to be retrieved.
`adjust`	a logical value. if `TRUE`, prices are adjusted for dividends and splits.
`verbose`	a logical value. if `TRUE`, then progress information is printed.

This is an unsophisticated wrapper for the getYahooData function in the TTR package.

An object of class xts with dates along rows and assets along columns.

Not formally tested.
