Branch for big updates, so that I can have broken intermediate states.

svn path=/branches/sredl_2009_05_proptree_update/boost/property_tree/; revision=53026
Lots of doc changes, and start of signature change.

svn path=/branches/sredl_2009_05_proptree_update/boost/property_tree/; revision=53028
Add allocator parameter, update some parts of the interface to the new parameter order, reflow ptree.hpp to 80 cols with 4-char indent.

More reformatting, and hopefully complete update to new template args.

svn path=/branches/sredl_2009_05_proptree_update/boost/property_tree/; revision=53032
Get property_tree back to compiling.

svn path=/branches/sredl_2009_05_proptree_update/boost/property_tree/; revision=53033
Start implementation using multiindex. Everything's totally broken right now.

svn path=/branches/sredl_2009_05_proptree_update/boost/property_tree/; revision=53095
Core ptree complete, but probably full of typos.

Copyright notices.

This is the fat rewrite. It compiles and the main test case passes. Peripherals (like parsers) not yet converted.
