Primary Focus: Shape expressions subset definition

This release focuses on defining the foundations for the future of language. Specifically, define the subset of the grammar that will be part of shex-lite.

As part of this release, therefore support for grammar and syntactic and semantic validations is included.

Grammar definition. The grammar is defined so that 80% of the most widely used functions of the shape expression language can be achieved.
Syntactic validation. In the compiler it is included a very first version of the syntax validation that allows to detect syntactic errors in given schemas.
Semantic validation. It is also included in this release a very first version of the semantic validation that provides help to developers to fix their schemas to avoid runtime errors.

Other Improvements

This release also includes a very basic CLI application that allows to use the compiler com the command line tool. The CLI tool includes the following instruction set:

Usage

 shexlc [options] <files> ... : compile and generate target domain model objects

Options

   -gd, --generate-domain-model-objects : if present will generate domain object models
   -hw, --hide-warnings                 : if present will hide the warnings

Arguments

   <files> : ShEx-Lite sources to compile

Usage Example

In order to execute this release two example shexl files are attached. To execute from CLI you just have to write:

java -jar shexlc-2.0-beta.jar

This will print the help page with all the instructions to compile the included files.
