Update the pin layout table and consolidate the RPi readme files. 

 - Changes in the pin layout table to describe how to connect the NRF24L01 pins to different boards
 - Remove duplicate readme information in the RPi readme file and point to the default RPi/RF24/readme.md file.

## Pin layout
The table below shows how to connect the the pins of the NRF24L01(+) to different boards.
CE and CSN are configurable.

# Optimized Raspberry Pi RF24 and RF24 Network Libraries
General Documentation: http://tmrh20.github.io
Library functions are mostly the same.
See the included examples for RPi specific usage
## Raspberry Pi - PreConfig
### Possible pre-configuration:
If SPI is not already enabled, load it on boot:
sudo raspi-config
A. Update the tool via the menu as required
B. Select Advanced and enable the SPI kernel module
C. Update other software and libraries:
sudo apt-get update
sudo apt-get upgrade
# RPi - RF24 Quick-Start
A. Make a directory to contain the RF24 and possibly RF24Network lib and enter it:
mkdir ~/rf24libs
cd ~/rf24libs
B. Clone the RF24 Repo
git clone https://github.com/tmrh20/RF24.git rtemp
C. Copy the RPi library folder to the current directory, and delete the rest
mv rtemp/RPi/RF24 ./
rm -r rtemp
cd RF24
D. Build the library, and run an example file:
sudo make install
cd examples
make
sudo ./gettingstarted
# RPi - RF24Network Quick-Start
A. Enter the same directory that contains the RF24 library folder
cd ~/rf24libs
B. Clone the RF24Network Repo
git clone https://github.com/tmrh20/RF24Network.git ntemp
C. Copy the RF24Network folder to the current directory, and delete the rest
mv ntemp/RPi/RF24Network ./
rm -r ntemp
cd RF24Network
D. Build the library
sudo make install
cd examples
make
sudo ./helloworld_rx OR sudo ./helloworld_tx
# Connection Info
Using pin 15/GPIO 22 for CE, pin 24/GPIO8 (CE0) for CSN
Can use either RPi CE0 or CE1 pins for radio CSN.
Choose any RPi output pin for radio CE pin.
**Constructor:**
RF24 radio(RPI_V2_GPIO_P1_15,BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ);
or
RF24 radio(RPI_V2_GPIO_P1_15,BCM2835_SPI_CS1, BCM2835_SPI_SPEED_8MHZ);
**Pins:**
| NRF24L01 | RPI | P1 Connector |
|----------|------------|--------------|
| VCC | rpi-3v3 | (17) |
| GND | rpi-gnd | (25) |
| CE | rpi-gpio22 | (15) |
| CSN | rpi-gpio8 | (24) |
| SCK | rpi-sckl | (23) |
| MOSI | rpi-mosi | (19) |
| MISO | rpi-miso | (21) |
See http://www.airspayce.com/mikem/bcm2835/index.html for BCM2835 class documentation.
Note: The BCM library has been customized slightly to allow use of hardware CE pins not
in use for SPI, and to include a millis() function.
****************
Based on the arduino lib from J. Coliz <maniacbug@ymail.com>.
the library was berryfied by Purinda Gunasekara <purinda@gmail.com>.
then forked from github stanleyseow/RF24 to https://github.com/jscrane/RF24-rpi
Network lib also based on https://github.com/farconada/RF24Network
Currently optimized and aligned with Arduino fork of libraries by TMRh20:
https://github.com/tmrh20/RF24/RPi and https://github.com/tmrh20/RF24Network/RPi
Documentation: http://tmrh20.github.io
