745b1b151d Add a small example to the parser test that shows that you do not need Sprit 
2's hold[] directve.  Fix an error exercised by the example.

3ebbd9e08c Correct an error in repeat_parser's choice of attribute. Sometimes it is 
necessary to use the value_type of the container out-param, rather than the
attribute generated by the subparser.

Fixes #52.

2b0053bf83 Add no_case[] directive, and associated changes to char, string, and boolean 
parsers to make it work; uses the recently-added Unicode case-folding
operation.  Needs docs.

d60d33e40b Finish implementing support for parsing into structs as if they were tuples. 
This makes it possible to map from sequence parsers onto structs with no
semantic actions.  Also, add a doc section describing how parsing structs
works (including a couple of short example programs).

Fixes #45.
Partially addresses #28.

f08255cf94 Use a tuple instead of a pair in seq_parser::{make_temp_result,combine}. Add a 
third tuple to the output of make_temp_result; this tuple is true/false values
indicating whether this parser's attribute was merged with an adjacent
parser's container of attributes of the same type.

2020e44fda Radically change the way that repeat_parser generates a sequence of 
attributes.  It now produces std::string when Attribute is char, and
std::vector<Attribute> otherwise (except for nope special-casing of course).

Partial fix for #36.

d34d4b7e6a Remove the seq_parser C<T> >> C<T> -> C<T> collapsing rule. Add special logic 
for recursive rules to make accumulating recursive parsers like
recursive_string_rule in the parser_rule test easier to write.

b7d1d3dba5 Fix spelling of hexadecimal 
The library and documentation misspells it (consistently, which is good
:)) as hexidecimal. That makes it hard for (new) users to find out by
searching documentation.

The fifteen spots fixed:

    example/callback_json.cpp|47 col 15| "four hexidecimal digits";
    example/callback_json.cpp|49 col 18| "\\uXXXX hexidecimal escape sequence";
    example/callback_json.cpp|51 col 38| escape_double_seq = "\\uXXXX hexidecimal escape sequence";
    example/json.cpp|57 col 28| // like "expected four hexidecimal digits here:", instead of "expected
    example/json.cpp|65 col 15| "four hexidecimal digits";
    example/json.cpp|67 col 18| "\\uXXXX hexidecimal escape sequence";
    example/json.cpp|69 col 38| escape_double_seq = "\\uXXXX hexidecimal escape sequence";
    example/json.cpp|158 col 18| // declare a hexidecimal parser that matches exactly 4.
    doc/tutorial.qbk|981 col 18| [ Matches a hexidecimal unsigned integral value. ]
    doc/tutorial.qbk|986 col 28| [ Matches exactly the hexidecimal unsigned integral value `_RES_np_(arg0)`. ]
    doc/tutorial.qbk|1118 col 42| So, if you wanted to parse exactly eight hexidecimal digits in a row in order
    doc/tutorial.qbk|2729 col 18| "\\uXXXX hexidecimal escape sequence";
    doc/tutorial.qbk|2731 col 38| escape_double_seq = "\\uXXXX hexidecimal escape sequence";
    doc/tutorial.qbk|2741 col 9| put a hexidecimal escape sequence there.
    include/boost/parser/parser.hpp|5622 col 13| /** The hexidecimal unsigned integer parser.  Produces an `unsigned int`

The one spot that was inconsistent (outside the gtest subtree):

    include/boost/parser/tuple.hpp|66 col 36| // 0xDEADBEEF (hexadecimal)
