With today's release of Elixir 1.3, now is a good time to drop compatibility
with much older releases. This also lets us use some of the nicer language
features introduced in Elixir 1.2, like the multi-alias syntax.
This PR introduces a parser based on @jparise's lexer. The parser
runs on thrift files and produces a set of Program models. The
intention is to be able to give Elixir full-fledged thrift support
and a better implementation.
This represents just the lexer definition. Full grammar parsing (i.e. yecc)
support will come later.
The lexer definition is largely complete, but there may be some issues with
string literals containing escaped characters \t and \n.
* add travisci support
* run code coverage post result to coverall.io
* add project info for hex package
