Fix misleading comment in sample code for collector example.

The analyze50 sub should be using the specified 50 passes, but
the comment says that it's using 10.
typo fix

I believe that the sentence is speaking about "the importer", aka
the person doing the importing, not "the import", possibly aka the
import statement above.

I guess "import" might be correct if one believe that the import
statement in a source file a) had a gender and b) was male.
flesh out the analyzer example a bit more completely

This adds the package (simple) and a call to Sub::Exporter (simple
if you understand what's going on, but if you're waffling it's nice
to have the clarity.
a bit of prose clarification

emphasize that C<import> is the name of a method and re-iterate what
exporting is
clarify; default was a bit overloaded in this sentence...
fix two typos that keep an example from compiling and making sense

Taken together these changes produce an example which can be used to do
what the cookbook claims it'll do.

* removed an extraneous '{'.
* replaced a "$class" (which isn't mentioned anywhere else in the
  example) with a "$pkg" (which is).
wordsmithing to better describe the example's goal and behaviour
fix a mismatch between the sample code and the docs
two fixups for pod for Sub::Exporter::Util::curry_chain

* need to quote 'results', fat comma's quoted the rest of the chain
  for you, but you're on your own with this one
* curry_chain takes a list, not an array ref
