Just added a simple statistics library to the playground. See http://
http://www.arduino.cc/playground/Main/Statistics


The lib calculates the average and stdev of a set of data(floats). It has a simple interface consisting of only six functions. An example sketch is added on the playground.

All comments are welcome,

You may want to use an unbiased stddev? i.e. use n-1 in the divisor.
