Fix package name conflict

[jjorn]

Problem

Due to the conflict between the main class name and package name, MungoHealer, the compiler is not able to access to a framework entity via package name i.e. MungoHealer.ErrorHandler, as described in thread #6.

Solution

Renaming the main class from MungoHealer to Mungo as suggested in thread #6.

Thanks for the PR, looks good overall. But it still doesn't explain why it didn't work earlier in the first place. It sounds like a bug in Swift to me if nothing else. So, either there aready is a related bug report on the Swift Forums / Swift JIRA or we should create one and link it within the issue, so we can track prograss and possibly revert the renaming, once it's fixed.

Yes you're right. Someone has found similar issue and already reported in SR-5304. Hopefully, it will be resolved in the next Swift version.

The issue is not critical. You can ignore this PR.

The issue seems to be open since quite some time now. So I'd say, we should fix it within this library nevertheless.

Plese rebase this. I'll merge once the CI passes.
