Optimizations and backward compatibility added (#3)

* Readings in example optimized; arduino version < 1.0 support; readme syntax and markdown error fixed and chaged; reorganized examples folder structure; keywords.txt added for keywords highlighting; I2C bus initialization moved into a library, so no need to initialize it separately

* Old files removed

* Markdown fixed

+GY-85 Arduino Library
+=====================
+A basic GY-85 raw data getter for arduino.
+
+Wiring for arduino UNO:
+
+GY-85   ->   Arduino  
+--------------------  
+VCC_IN  ->   5V  
+GND     ->   GND  
+SCL     ->   A5  
+SDA     ->   A4  
+
+For other arduino boards you have to check the I2C pins.
+
+Installation
+--------------------
+Download library and move it to your Arduino/libraries folder
