The pyDeco system is an opensource descompression system wrote on Python programming language
there will be 4 phases
[phase 1]
Generate a simple Nitrox calculator for reacrational divers that will calculate Maximun Depth when user inputs percent of O2 on the mix following rule:
((maxO2PressureOnTheDive/mixO2Pressure)-diveAbsolutePressure)*DephtEquivalantto1Atm
Calculate the Air Equivalent Depth when using Nitrox
AED = 1-PPO2*0,79
[phase 2]
Generate a deco system using the algorithm  found here http://www.lizardland.co.uk/DIYDeco.html
[phase 3]
Preapre a webservice using the software on the phase 2
[phase 4] 
Integrate more descompression algorithms
