Escaping

Escaping is a way to tell a computer to perform some special function 
or to ignore the sepcial funtion of a character.  Mostly we escape 
using the backslash (\).

The following escape sequences have special meaning:
\n - newline
\t - tab
\r - cariage return
\\ - print a real backslash
\" - ignore the " (usually a double quote ends a string by escaping the double quote
     the computer knows that the string carries on).  Eg "We \"helped\" him" would
     be displayed as - We "helped" him

\uxxxx - Unicode character.  Sometime you want to refer to unicode characters
	 normal ASCII.  Many programs and programmers use \u to refer to the
	 Unicode character.  Where xxxx is the hexidecimal value for that Unicode
     character.
