Function arguments have multiple coding standard. One of them is prefixing all function arguments with i or o. This is a naming convention I learned at work and I do not think it is largely used in the outside world. The goal is to prefix variables with an i when the variable is an input and an o when the variable is an output (like Parse() functions defined in RapidAssist).

I consider removing the i and the o prefixes as I don't think it is intuitive enough for people outside of my work environment. I am also not always consistent across all files.

We might also adopt function arguments naming convention defined in Google's C++ Style Guide.
