touch commit
fully tested working DHT11/21/22 with built in '2 second' timer
Example sketch
added mini readme
clarified the pullup
Arduino 1.0 compliant
Modified readTemperature() prototype.  Added prototype for new function.
Added option for converting to Fahrenheit
Merge pull request #3 from leprasmurf/master

Convert Celcius to Fahrenheit.
Default argument for compatibility with old sketches
Prevent dht.h being imported multiple times

Added a basic #ifndef DHT_H to the dht.h file so that if you have a
larger program and want to access the sensor from a different file, you
don't import it twice.
Merge pull request #4 from Jearil/master

Adding #ifndef DHT_H to header file
Support for non 16mhz devices

Added constructor parameter to allow for different timing needs. It has
the a default value of 6 which is the original value, so it should be
backwards compatible
Merge pull request #8 from soerup/master

Support for non 16 MHz devices by adding extra parameter to constructor
Change example extension from .pde to .ino.
Update example to show temp in Fahrenheit and add computeHeatIndex function to resolve issue #9.
Remove serial.print from library and update example error handling. Resolves issue #11 and #13.
Switch to use noInterrupts and interrupts function. make read() public.  This resolves pull #15.
Resolve issue #20 by moving delay after 2 second read check to make read return quickly.
Resolve #24 by adding convert F to C function.
