[SoC] Week 7 Report - Full support of Python 3 in GRASS GIS

[Sanjeet]

Hi everyone,

This is my week Week 7 report for the project "Full support of Python
3 in GRASS GIS"

1) What did I complete this week?

    Updated ctypes to deal with bytes[0]
    Worked on 'temporal' library [1], lot of errors were encountered
    Looked into issues for 'pygrass' testsuites which were failing too
    Created a spreadsheet[2] detailing errors and information
regarding the temporal testsuites
    Also, updated the pygrass testsuite details on spreadsheet[3]

2) What am I going to achieve for the next week?

    Start exploring GUI library, starting with mapdisp and imgr
    Continue working on fixing ctypes module
    Continue working on 'temporal' library

3) Is there any blocking issue?
    Ctypes are not fully compatible with the Python3 even if they are
compiling without any issues. Discussed witb mentors about the next
steps and how to deal with ctypes.
    Will discuss more about the upcoming milestones and how ctypes
handling is to be done so as not to interfare too much with the
pending work.
