This has been inspired by MODDMA example4.h.

Some differences compared with the MODDMA example: 1) this DMAFuncGen class can work using dma alone (no ISR required, although there is a callback routine included if you would like to synchronize something to the function generator), and 2) there is only one buffer (not two).

It is intended for the LPC1768. It has been tested and seems to work fine.
