Matthias Beyer 0e20b25091 Add extension traits for handling Result<Option<T>, E> conversion 
This extension traits help transforming Result<Option<T>, E> to
Result<T, E> or transforming an iterator over the former type to an
iterator over the latter type.

Should be moved to resiter of course, but we need to implement this
first.

libimagerror

In imag, we do not panic.

Whatever we do, if we fail as hard as possible, the end-user should never ever see a backtrace from a panic!().

Anyways, the user might see a error trace generated by imag. That is because imag is software for power-users, for nerds (I use the term "nerd" because for me it is a good thing - I do not want to offend anyone by using it). This target group can read backtraces without getting confused. IO Error and Permission denied Error are things that nerds can understand and they already know what to do in the most obvious cases (such as Permission denied Error).

This library crate is for generating error types and handle them in a nice way. It can be seen as mini-framework inside imag which was written to work with error types in a specified way. All imag crates must use this library if they can return errors in any way, except the libimagutil - which is for the most basic utilities.
