Removed some unneeded methods, due to the previous refactor involving shared_ptr objects. They no longer require some special overloads which "delete" the objects in the cache.

Yet another huge refactor, to use shared_ptr objects instead of actual pointers, due to the difficulties in managing the lifecycle of pointers between the timeline, clip, and readers. Seems to work great, and solves all sorts of bugs. =)

Fixed a regression with audio files and seeking, added a few new methods, and more accurately detect the End() of clips.

Fixed a regression with disabling seek on the FFmpegReader. It runs slower than seeking, but has no artifacts of seeking, and is frame accurate.

Fixed the seeking and cache code to work correctly. Also fixed a huge memory leak with the new AVPicture structs. Now the time mapping works both directions, and with no major memory leaks!

Another huge refactor and lots of big fixes! Time mapping now works... mostly. The jumpy / glitchy images have been solved by copying the AVFrame into an AVPicture, which does not get clobbered on the next decode.
...
Also, added a new frame number overaly (in the top, left part of the image), and a new AddColor() method, to change the size and color of the frame's image...
Padded the end of the FFmpegWriter / WriteTrailer() method, to avoid having a codec ignore the last many frames.

Major refactor to the cache object (again)! It now uses bytes to determine how many frames to keep.

Refactored seek method a bit in the FFmpegReader, to fix some bugs. Also, being changing the cache object again, on how it cleans up pointers. Some debug code is checked in also.

Added new method to adjust the min value of a valid frame number, added a new unlimited cache option, and fixed a bug which was preventing the timeline from calling GetFrame correctly. Now timelines, clips, and readers are working together nicely.

Fixed a regression with the FFmpegReader, to always get frame 1 first, to calucate the PTS offsets, etc... Also, fixed a bug on the timeline, and now i'm 1 step closer to having it all work. =)

Added a FrameRate() method to the timeline, to get or set the fps. Also, added a unit test for that, and refactored some header files to be alphabetical.

Refactored constructor() methods on readers again, to call Open() and then Close() methods automatically, to populate the info struct. And moved the GetFrame() call out of the Open() method, because it was unneeded and slowed down the Open() method.

A big refactor of the Open() method on Readers, and the constructor of Readers. All resource consuming code has been moved into the Open() methods, so the Clips and Timeline can control them better.

Protected the Open() and Close() methods better, so the FFmpegReader will not crash. Also, made the Open() method public, so the Timeline and Clip classes can control the reader better.

Enabled multi-threading decoding and encoding with libavcodec, setting the thread_count property. This make a huge improvement in CPU performance, for codecs that support this property.

Fixed a big regression where the "omp" tag was not correct. Also, restructured the encoder to be much faster, and changed "omp master" to "omp single".

Improved the multi-threaded code, by requiring a minimum of 8 frames to be processed by the reader.

Added a minimum # of packets to read in the FFmpegReader, which really helps utilize the multiple threads... and improved performance by 27% overall.

Huge refactor, switched almost all methods to using pointers for Frames, and moved some key method calls outside the critical OMP sections. Also, refactored the sws scaler, to create a pool of 32 scalers, and give each thread it's own scaler. This refactor resulted in a 40%+ increase in speed on the FFmpegReader class.
...
I also added a cmake build flag for the google perftools library, to assist on profiling performance issues.
