Automatic actigraphic recording analysis

In other words, given actigraphic recodings, detect the sleep/wake periods in an automatic way.

Limitations/warnings:

So far

• the development were tested on only one kind of actigraphic recordings (from ActiWatch to be precise)
• it works and assumes that sleep patterns are regular and were acquired on a 'normal healthy' subject. All in all, the following 2 hypothesis are used: sleep for about 33% of the time in long continuous spell.
• some bit of code are hard-coded for a sampling interval of 60s. Hopefully this constraint will be (easily) lifted...
• for file selection, the code use the function spm_select from the SPM package. Should be replacable by the 'uigetfile' function from Matlab at some point...
