// OLD:
// binder is used during the conversion of an ABI definition into Go bindings
// (as part of the execution of BindV2). In contrast to contractBinder, binder
// contains binding-generation-state that is shared between contracts:
//
// a global struct map of structs emitted by all contracts is tracked and expanded.
// Structs generated in the bindings are not prefixed with the contract name
// that uses them (to keep the generated bindings less verbose).
//
// This contrasts to other per-contract state (constructor/method/event/error,
// pack/unpack methods) which are guaranteed to be unique because of their
// association with the uniquely-named owning contract (whether prefixed in the
// generated symbol name, or as a member method on a contract struct).
//
// In addition, binder contains the input alias map. In BindV2, a binder is
// instantiated to produce a set of tmplContractV2 and tmplStruct objects from
// the provided ABI definition. These are used as part of the input to rendering
// the binding template.
// NEW:
// binder is used to translate an ABI definition into a set of data-structures
// that will be used to render the template and produce Go bindings. This can
// be thought of as the "backend" that sanitizes the ABI definition to a format
// that can be directly rendered with minimal complexity in the template.
//
// The input data to the template rendering consists of:
// - the set of all contracts requested for binding, each containing
// methods/events/errors to emit pack/unpack methods for.
// - the set of structures defined by the contracts, and created
// as part of the binding process.
