Arduino Style Library for STM32F0x

I've added examples for people to get started for different peripherals

the examples are added in the example directory in the repo and example Group in the IDE

to use each example one by one you have to follow these steps

1. highlight the example that you want to use and right-click and go to options for the example.
2. the options window on the TOP- LEFT corner has a checkbox "Exclude from build" Uncheck that and compile
3. please make sure to not have more than one active example that is included in the build because that would make the project to have multiple declarations of ' main() '

i'm currently working on the input Capture feature of the timer to getFrequency and getDuty of an input PWM wave its a WIP but the PWMout or analogWrite works!! so cheers !!
