Naming functions with `omf.` namespace.

Having a clear namespace `omf.` improves the readability of the code as
we clarify what is the function name and what is the namespace.

+`fish` does not have private functions, so in order to avoid polluting the global namespace, use double underscore before your function name. For example, if you are writing a `ninja` plugin using `__ninja.function_name`.
 
 Note that it's still possible to mimic private functions in `fish` by deleting the function before returning using `functions -e function_name`
