Add visualization tools for ipython
Start a test of stencil_grid for ctree
Merge branch 'master' of github.com:ucb-sejits/ctree
add explicit Python version check
close to array doubler. generated code is correct but ctypes type checking fails on numpy array
array doubler works!
doubler works for ints, floats, and double arrays
move numpy.dtype -> ctype mapping to ctree.types
enable 'static inline' on ArrayDoubler::apply function to trigger inlining. Bumped the optimization level to 3 so now the code auto-vectorizes. Huzzah!
get all examples working again
