ModelResources, in line interface to define schema, improved http router

• Introduced ModelResource. Just specify a model_cls on the Resource and voila, you have a fully functional http CRUD api
• Inline interface to define a schema. No need to define a schema class independently - that had very little utility anyway
• Http routing is much more cleaner with a Router. Now url resolution is also not hardcoded into ResourceUri field.
• All the functionality of Router, ModelResource, CrudResource etc is highly customisable with overridable classes.
