Refactor blueprint parser nodes to an interface Refactor the blueprint parser Value object, which contained a Type enum and members to hold every possible type, into an interface (now called Expression). Rename the existing Expression object that represented a binary operator Operator. Also adds and fixes some new printer test cases with mulitline expressions.

Blueprint is a meta-build system that reads in Blueprints files that describe modules that need to be built, and produces a Ninja manifest describing the commands that need to be run and their dependencies. Where most build systems use built-in rules or a domain-specific language to describe the logic for converting module descriptions to build rules, Blueprint delegates this to per-project build logic written in Go. For large, heterogenous projects this allows the inherent complexity of the build logic to be maintained in a high-level language, while still allowing simple changes to individual modules by modifying easy to understand Blueprints files.
