title: Create an array or List of all dates between two dates
body: <p>I am generating multi-series graphs with the date along the X-Axis.  </p>
  
  <p>The problem is that not all of the series in the graph have the same dates in the date range.  Meaning that if I choose 1 Feb through 30 Apr that one series may have data that starts at 1 Feb but only goes through the end of March but another series may have data for the entire date range.  </p>
  
  <p>This skews the charts I need to create.  Go, given the date range taken at the begining of the query I'd like to generate a list of dates and populate the data to be graphed, padding those series with 0's for those dates that have no data.</p>
