Unicode

 - Unicode supported by Gfortran only, but gracefully handles Intel
 - Currently this will build, run and pass the tests with gfortran 4.9.2_1
 - Actual deferred length character arguments corresponding to `intent(out)`
   dummy arguments _**MUST**_ be of kind `CK` to ensure proper functionality
 - All `intent(in)` character arguments to the public API may be of kind
   'DEFAULT' or CK
 - If unicode is enabled, files use utf-8 encoding
 - Fixes #79 : API discrepancy between get methods and get vec methods.
   Now the path argument is optional for both
