skydarc meneldoll / Mbed 2 deprecated IQS572_HelloWorld

this is a first compilation of a library for IQS5xx. For now, it work with the iqs572ev02 devellopment board. The code is inspired with the sample code provide by Azotech. I have some issu with the interrupt pin RDY, which seem to be high even I don't touch de board.

Dependencies:   mbed
