work in progress

arima.py
^^^^^^^^

ARIMA : initial class, uses conditional least squares, needs merging with new class
arma2ar
arma2ma
arma_acf
arma_acovf
arma_generate_sample
arma_impulse_response
deconvolve
index2lpol
lpol2index
mcarma22

movstat.py
^^^^^^^^^^

I had tested the next group against matlab, but where are the tests ?
acf
acovf
ccf
ccovf
pacf_ols
pacf_yw

These hat incorrect array size, were my first implementation, slow compared
to cumsum version in la and cython version in pandas.
These need checking, and merging/comparing with new class MovStats
check_movorder
expandarr
movmean :
movmoment : corrected cutoff
movorder
movvar
