makeChart created working and unit tested

"""Takes a dictionary with the subset of data that we want and makes a
chart
    Input : chartableDict which can have special entries

"control chart title" => the title of the new chart,
            if
absent or blank title will be 'chart title'
        "control chart
options" => the options to be sent to google charts,
            if
absent or blank defaults will be used
        all other keys are labels
for the new chart, and correspond to data points.
    Output: a file
named whatever the chartableDict['control chart title'] + '.html',

or, if absent or blank, chart\d+.html w/ \d+ as lowest possible choice
starting at zero
