Responsive default size

this component uses the react-native-pixel-perfect

and the defualt style is using base resolution for iphone7, in case you want to use the default design but, using a different base resolution, I added a function called updateBaseResolution(width,height) to use it you need to access it via a ref to the component.

since the component is dependant on react-native-pixel-perfect, when installing this package you install also react-native-pixel-perfect if it's not already installed.

so you can create your own responsive size function and use it to set your custom style.

* value prop - this component uses it's own state to hold value if value is not given as a prop
* style props - this component has a default style and the styles props are to override the default style or add more fields
* totalWidth prop - this prop is for the entire component width, and all other sizes are derived from it , unless given other size props
* initValue prop - if using value prop, this is not needed and the initial value can be given by the value prop
