String
======
Description
-----------
The String class, part of the core as of version 0019, allows you
to use and manipulate strings of text in more complex ways than
`character arrays <http://arduino.cc/en/Reference/String>`_ do. You
can concatenate Strings, append to them, search for and replace
substrings, and more. It takes more memory than a simple character
array, but it is also more useful.
For reference, character arrays are referred to as strings with a
small s, and instances of the String class are referred to as
Strings with a capital S. Note that constant strings, specified in
"double quotes" are treated as char arrays, not instances of the
String class.
