add ability to dump xml metadata for stage
add a Metadata::to_xml method, this is duplication of the pipelinewriter static method of the same name, but I think these should probably be pulled closer to the objects themselves than out in some auxillary class
add --xml switch to support XML output in addition to JSON
to_json method for pdal::Metadata
add mersenne twister to the pdal::Environment so we can easily reuse it for uuid creation instead of having to create one for every uuid we create
add a pdal::Object ultimate base class that all of our major objects will eventually derive from
recognize the XYZ writer driver
handle missing option sensibly
commentout busted test for now
boost:: prefix for cstdint data types so we can compile on MSVC 2008 from Kevin Murphy
add an example predicate for keeping specified classifications
add examples for filtering to keep last returns or specified return values
add metadata entries for stats filter options
add stats filter to example
support writePipeline transparently writing to stdout via special filename
remove the note to stdout about how many points are written. We want pcpipeline to take in stuff via stdin and write out pipeline serializations via stdout.  notices should probably go to stderr
remove -pedantic for now
ignore unused
add -Wextra
use std::string instead of char* to back up source, function, and module
