PWM frequency library

Thank you so much for this library as it has been fantastic in helping me get a pump driver up and running.

I have a question regarding timers using the 328. I have noticed that the library functions do not allow you to set the frequency on TIMER2A and was wondering if there was a specific reason why the library would not allow you to set this timer as I can't really find a default use for TIMER2A that would interfere with any other arduino function.

Thanks,
