Consolidate code generation in newtgenerator

[rsdoiel]

I don't want a sprawling set of tools. Code generation should be done in one program that can return the desired code. E.g. newtgen [CODE_TYPE] [NEWT_YAML_FILE]

Still evolving what the command line syntax looks like.

newtgen YAML_FILE TARGET [PARAMS]

For generating Postgres+PostgREST configurations we have several file types being generator, "setup.sql" (this should not be checked into your repository), "models.sql" (should be included in a repository), "models_test.sql" (should be included in a repository) and "postgrest.conf" (or similar name, might be included in the repository). E.g.

newtgen app.yaml postgres setup >setup.sql
newtgen app.yaml postgres models >models.sql
newtgen app.yaml postgres models_test >models_test.sql
newtgen app.yaml postgrest conf >postgrest.conf

For the Mustache templates I think a similar approach is called for except the templates would be derived from the CRUD-L operations combined with a model name. In this example the model id is "people".

newtgen app.yaml mustache create people >create_people.tmpl
newtgen app.yaml mustache read people >read_people.tmpl
newtgen app.yaml mustache update people >update_people.tmpl
newtgen app.yaml mustache delete people >delete_people.tmpl
newtgen app.yaml mustache list people >list_people.tmpl

This would keep the existing YAML as is and solve the problem of how a specific project might need to name or organize their source files.
