 Gorgonia works by creating a computation graph, and then executing it. Think of it as a programming language, but is limited to mathematical functions, and has no branching capability (no if/then or loops). In fact this is the dominant paradigm that the user should be used to thinking about. The computation graph is an [AST](http://en.wikipedia.org/wiki/Abstract_syntax_tree).

 We use [semver 2.0.0](http://semver.org/) for our versioning. Before 1.0, Gorgonia's APIs are expected to change quite a bit. API is defined by the exported functions, variables and methods. For the developers' sanity, there are minor differences to semver that we will apply prior to version 1.0. They are enumerated below:
 
-* The MINOR number will be incremented every time there is a deleterious break in API. This means any deletion, or any change in function signature or interface methods will lead to a change in MINOR number. 
+* The MINOR number will be incremented every time there is a deleterious break in API. This means any deletion, or any change in function signature or interface methods will lead to a change in MINOR number.
 * Additive changes will NOT change the MINOR version number prior to version 1.0. This means that if new functionality were added that does not break the way you use Gorgonia, there will not be an increment in the MINOR version. There will be an increment in the PATCH version.
