 * Interpolates a data list, filling in the specified multiple.

 * The input does not have to be numeric, but if it isn't an accessor function should be supplied.
 * Note that this just performs linear interpolation
 * @param data - Array of objects to compute interpolated values for
 * @param multiple - Multiplier, e.g., 2 means to "double" the length of the array by puttting a value between each value
 * @param accessor - Accessor function to return a numeric property value, if the input data is not numeric
