Commit: `c700f61`

Storage.DeleteAll method for removing all docs
Deprecated bool from Storage.ImportDocs(string,bool)
for now we keep this for compatibility
Included multiple tests for the multi-doc methods
Moved tests under tests directory
Removed returning an error from Global wrappers

Ensure that AddDoc() and Switch will not return null pointer
when the library is empty

In this commit we consolidated the getFn and wrapErr
functions into a new function called WrapErr

In addition to the above change WrapErr handles
the error creation automatically.

Before we were creating the error from in the caller
and then passed it into the wrapErr function together
with the result of getFn

Now we are only passing the error/string + additional
arguments if required and call create the error withing
WrapErr

Add emptyMap function
