A new function profiling system is implemented. Most importantly, this
allows one to profile various internal functions directly by setting the
`PYQTGRAPHPROFILE` environment variable to a comma separated list of
function and method names, e.g.
PYQTGRAPHPROFILE=functions.makeARGB,ImageItem.render \
python -mexamples
Specifically, items in `PYQTGRAPHPROFILE` must be of the form
`classname.methodname` or `dotted_module_name.functionname`, with the
initial "pyqtgraph." stripped from the dotted module name.
Moreover, the overhead of inactive profilers has been kept minimal: an
introspective check of the caller's name (only if `PYQTGRAPHPROFILE` is
set) and a trivial function (not method) call per profiler call.
The new profilers rely on `sys._getframe` to find the caller's name,
although the previous system (passing the caller's name explicitely)
could certainly have been kept instead.
Finally the API of profilers has been changed: register a
profiling point simply by calling the profiler, and profilers are
automatically flushed on garbage collection. See the docstring of
`pyqtgraph.debug.Profiler` for more details.

Installation Methods
- To use with a specific project, simply copy the pyqtgraph subdirectory anywhere that is importable from your project
- To install system-wide from source distribution:
$ python setup.py install - For instalation packages, see the website (pyqtgraph.org)
Documentation
There are many examples; run python -m pyqtgraph.examples for a menu.
Some (incomplete) documentation exists at this time.
- Easiest place to get documentation is at http://www.pyqtgraph.org/documentation
- If you acquired this code as a .tar.gz file from the website, then you can also look in doc/html.
- If you acquired this code via GitHub, then you can build the documentation using sphinx.
From the documentation directory, run:
$ make html
