Read laser hours of all lasers

[Francissss]

• Should query laser head wavelength using ?HID and sn?, and then get laser hours.
• Format output in a nice table.
• Will need to import serial and re.

You made good progress on Friday. Regarding the difference in string handling you noticed between Python 2.7 and Python 3.4: the specific is documented and discussed [upstream](https://en.wikipedia.org/wiki/Upstream_%28software_development%29 upstream) here: http://sourceforge.net/p/pyserial/bugs/106/

Best practise is to check-in your code often (try to follow the UCSF recommendation of doing it at least at once a day even if the code is worse off than before). Since your work is pre-alpha, instead of adding code into the master branch you should create a new branch: https://help.github.com/articles/fork-a-repo#create-branches I believe you would have to create the branch from the command-line. GitHub for Windows used to install a separate start menu shortcut to take the trouble out of running git this way, but if I remember correctly, one can now do this from within the GitHub GUI instead (probably by right-clicking on the project). Name branch after the feature you are adding.

Once you have your code checked in I will be able to add comments inline, online.

You've made good progress on the program, and there are a fair number of changes I've suggested you make. Hopefully you have a chance to test it out soon in the field.
