'Write the OHLCV data for the given sid.
If there is no bcolz ctable yet created for the sid, create it.
If the length of the bcolz ctable is not exactly to the date before
the first day provided, fill the ctable with 0s up to that date.
Parameters
sid : int
The asset identifier for the data being written.
dts : datetime64 array
The dts corresponding to values in cols.
cols : dict of str -> np.array
dict of market data with the following characteristics.
keys are (\'open\', \'high\', \'low\', \'close\', \'volume\')
open : float64
high : float64
low  : float64
close : float64
volume : float64|int64'
