SSP and g.part6 expanded with calculations of alpha_1 and alpha_2, output keeps the same convention that was used: SSP and ABI, and adds SSP_short/long, and ABI_short/long

update documentation of DFA analysis

Move fluctuation analysis to DFA and keep only slope calculations in SSP (suggested by Vincent)

Revised the returned value of DFA in the documentation, it returns the matrix with box sizes and amplitudes, not the alpha (alpha is calculated in SSP)
