Made a minor modification to the effect of maria exporting grail's
`find` and `findAll` methods on the maria namespace object.  Also
modified Makefile to ensure these changes are added to the build.
Fixed small bug in exporting grail methods (maria.findAll referred to maria.find)
Merge pull request #69 from VincentToups/master
