Proposal: Renaming "Patlet" to "Summary"

In our pattern template we have a section called Patlet. We define it as:

Concise 1-2 sentence description of the problem and solution. Readers may quickly review dozens of these patlets to discover and browse the larger library of patterns. http://wiki.c2.com/?PatLet

However many readers find this confusing, as Patlet is no real word in Englisch, and does not have an intuitive meaning. So while the word Patlet is kind of cute, and maybe fun for some of us (hardcore pattern nerds that is :)), it is not very helpful for the average consumer of our patterns.

Therefore I propose to replace the word Patlet by Summary instead.

Here is how I propose to change the definition in the pattern template.

-## Patlet
+## Summary

-Concise 1-2 sentence description of the problem and solution.
-Readers may quickly review dozens of these patlets to discover and browse the larger library of patterns.
-From http://wiki.c2.com/?PatLet
+Concise summary of the pattern.
+Use the first sentence to describe the **problem**, the second sentence to describe the **solution**.
+Readers may quickly review dozens of these summaries to discover and browse our library of patterns.
