Fixed problems with newer versions of avr-gcc.

Fixed compatibility problems with Arduino 1.5.2 beta.

Added documentation.

Code cleanup.

6 Jan 2012

Made buffer indice type an option (uint8_t or uint16_t) with
#define ALLOW_LARGE_BUFFERS
 
Added defines to hide templates:
/** Define NewSerial with buffering like Arduino 1.0. */
#define USE_NEW_SERIAL SerialPort<0, 63, 63> NewSerial
/** Define NewSerial1 with buffering like Arduino 1.0. */
#define USE_NEW_SERIAL1 SerialPort<1, 63, 63> NewSerial1
/** Define NewSerial2 with buffering like Arduino 1.0. */
#define USE_NEW_SERIAL2 SerialPort<2, 63, 63> NewSerial2
/** Define NewSerial3 with buffering like Arduino 1.0. */
#define USE_NEW_SERIAL3 SerialPort<3, 63, 63> NewSerial3
 
Added HelloWorld example.

Modified several examples.
 
Internal changes based on running Google's style program cpplint.py.

Added examples:

ReadWriteTest
WriteFlash

Added functions:

size_t write_P(PGM_P b, size_t n);
size_t write(const __FlashStringHelper* s);
size_t writeln(const __FlashStringHelper* s);

fixed bug in size_t read(uint8_t* b, size_t n)

Almost total rewrite so expect bugs!  Be sure to tell me about bugs.

See html for more details about the following functions.

Changed begin() to have a optional second argument to set parity,
character size, and number of stop bits.

void 	begin (long baud, uint8_t options = SP_8_BIT_CHAR)

The following can be ORed together for options:

Choose one stop bit option.
static const uint8_t 	SP_1_STOP_BIT = 0 (default)
static const uint8_t 	SP_2_STOP_BIT = M_USBS

Choose one character size.
static const uint8_t 	SP_5_BIT_CHAR = 0
static const uint8_t 	SP_6_BIT_CHAR = M_UCSZ0
static const uint8_t 	SP_7_BIT_CHAR = M_UCSZ1
static const uint8_t 	SP_8_BIT_CHAR = M_UCSZ0 | M_UCSZ1

Choose one parity option.
static const uint8_t 	SP_EVEN_PARITY = M_UPM1
static const uint8_t 	SP_NO_PARITY = 0
static const uint8_t 	SP_ODD_PARITY = M_UPM0 | M_UPM1

Added RX error checking.

The following error bits are returned:
static const uint8_t 	SP_FRAMING_ERROR = M_FE
static const uint8_t 	SP_PARITY_ERROR = M_UPE
static const uint8_t 	SP_RX_BUF_OVERRUN = 1
static const uint8_t 	SP_RX_DATA_OVERRUN = M_DOR

Added the following functions:

void clearRxError()
uint8_t getRxError()
size_t 	read (uint8_t *b, size_t n)
size_t 	write (const char *s) - overrides version in Stream
size_t 	write (uint8_t *b, size_t n) - overrides version in Stream
size_t 	writeln (const char *s)
size_t 	writeln ()
