Closing the Grant

With the following commit I am closing the grant.

This is what has been accomplished from each of the objectives:

• Cleaner Code and a lot of memory and performance improvements ( SDL 2.527 released Jan 18th )
• 10 out of 11 chapters completed:
• The profiling chapter was dropped as there was not enough content to justify a chapter.
• 3 Extra chapters added.
• Deviation from a CPAN SDL::Manual release due to the nature of the Manual it is being released as a creative commons book instead.

Next Steps:

• Get the book polished and edited with chromatic's help
• Fix build system of the html to make a real SDL::Manual release
• Constant update of the book with more releases of SDL and reviewer comments.
