Fixing emacs metadata for tests
Merge branch 'master' of github.com:ContinuumIO/blaze-core
Small improvement to some exception messages
Add support for parsing the 'string' datashape as proposed

In doing so, I've moved some of the datashape construction
into the PLY semantic actions, in particular for the 'appl_args'
production rules. I think it might make sense to move all of
the build_ds functionality there, to make it easier for
people to see what's going on.
Fix how the String datashape object converts to a string
Fix out of bounds array access on end-of-string parse error
Add the ability to name datashape record fields 'type', 'int32', etc
Fix the line number/pointer in the datashape parse syntax error
Merge pull request #41 from mwiebe/string_dshape

Add string dshape support
Remove C extensions from setup.py which prevented build on Linux and Windows
Improve repr of some datashape objects, improve some exception messages
Convert the datashape parser semantic actions to generate the final datashape objects

As a side effect, this fixes some bugs in parsing fields which are arrays
Tweak some tests, and add more for datashape construction/parsing
Bugfix in test on non-Win platform
