added more concise methods for querying the ast
better warning messages for method decls that aren't annotated with types
checkpoint: initial attempt at lazy tree building to harvest arg types
move stuff from example file into main directory
put verification on pure C ast in library, not specializer
use C doubles as equivalent types to Python floats
make LazySpecializedFunction accept an ast.Module
rip out ctree Type hierarchy, opt for using ctypes types directly
get examples working with new type representation
better warning message for non-C asts
more info in DOT files for python asts
auto dedent program text, implement more standard interface to ArrayDoubler specializer
new transformer to strip python docstrings
ignore .ds_store files
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
