Two co-addition and image subtraction codes: properimage and ois

Difference Image Analysis and image co-addition are key time-domain astronomy tasks and
the latest techniques are usually implemented as components of larger pipeline
software frameworks.
This work presents two standalone software projects that deliver simple
to use state of the art image subtraction and addition implementations.
As a strong key point of this work is the use of open source and tested software,
with focus in building reliable and maintainable tools for small observational projects.
