+## NeoPixelBus\<FEATURE, METHOD\>(uint16_t countPixels, uint8_t pin) 
+This will define the object with the given Feature and Method, and construct it to handle the countPixels on the given pin.  
+countPixels - The number of pixels on the physical bus.  This is limited primarily by memory to contain a buffer for them.  Some Methods (ex. NeoEsp8266Dma800KbpsMethod) require more buffer than others and you should refer to their documentation.  
+pin - The output pin to use.  Note that some platforms and Methods restrict the Pin and thus will ignore this parameter.  On Esp8266, Neo800KbpsMethod is the same as NeoEsp8266Dma800KbpsMethod; which has the restriction of using GPIO3 pin only and thus it will ignore this parameter.

 ## void Begin()
 This will initialize the NeoPixelBus and prepare it for use.  Call this first within Setup().
