     * @param _prices 2 element Array comprising a min price and max price in atto units in order to support decimal values. For example if the display range should be between .1 and .5 the prices should be 10**17 and 5 * 10 ** 17 respectively
     * @param _numTicks The number of ticks for the market. This controls the valid price range. Assume a market with min/maxPrices of 0 and 10**18. A numTicks of 100 would mean that the available valid display prices would be .01 to .99 with step size .01. Similarly a numTicks of 10 would be .1 to .9 with a step size of .1.
     * @param _extraInfo Additional info about the market in JSON format.
     * @return The created Market
