Releasing 3.0.0

DistanceRead is now Read() [#47]

• To simplify the name of the distance read method to read()
  Documentation, examples and other references have been updated.
  The old method still works, but a depreciation message is launched.

Abolition of the pulseIn method [#45]

• The implementation of the timing now no longer use pulseIn() to prevent any incompatibility problems with platforms that do not have this method implemented.

Other changes

• Added WProgram.h to header file to increase code compatibility [#46];
• Created examples using timeouts [#44];
• Created code of conduct, instructions to contribution and issue templates;
• Some fixes in documentation and code style.

My thanks to the contributions of the whole community, especially @OtacilioN and @per1234 🖖

Releasing 2.1.0

Add timeout to prevent lock-up

Prevents lock-up when waiting for echo return. Delegated Ultrasonic constructor for three-pin operation

The timeout is an optional parameter (20000UL by default) in the constructor or defined at runtime.

On the constructor:

Ultrasonic ultrasonic(12, 13, 40000UL);

Or in runtime:

ultrasonic.setTimeout(40000UL);
