[DIMENSION STANDARD_DEV] = fractalvol(DATA) calculates the fractal dimension of the 1 dimensional random walk, DATA. DATA is assumed to be a function of its indices.
Finds fractal volatility by embedding in the unit square and box
counting. Y axis will be rescaled values of DATA, x axis is
(1:length(DATA))/length(DATA).

Uncomment the else construction if you have the parallel computing
toolbox and wish to run the code in parallel (it scales linearly in instances).
