Create a plot showing the improvement of groups relataive to the total population

1	timeChangePlot(data1, data2, values, type, grain = 20)

`data1`	is a full dataframe with data on toxicity concentration and population counts. The dataframe must contain the variables: 'lconcentration' and the count of total population 'tot_pop'
`data2`	is the same format of data, but at a second time period, over which you are interested in the changes
`values`	is a vector of strings refering to the columns you would like to see the relative changes in. All strings must match to a column in the dataframe.
`type`	should be either "rank" or "value".
`grain`	defines how fine grain you want the calulation to be. No input will default to 100 calculations

Returns a plot object, showing the differences in changes in the groups, that can be saved or directly displayed. Returns a positive 'value' difference if group 1 improved more than group 2 over the interest period.Returns a negative 'rank' difference if group 1 improved more than group 2 in the defined time period.
