// Package wickra provides idiomatic Go bindings for the Wickra
// technical-analysis library over its C ABI hub.
//
// Each indicator is an opaque-handle type with a New<Indicator> constructor and
// Update/Batch/Reset/Close methods. Handles are freed by Close and, as a
// backstop, by a finalizer; call Close explicitly to release native memory
// promptly. The binding links against the prebuilt Wickra C ABI library
// (libwickra.so/.dylib or wickra.dll) staged under ./lib — see the package
// README for how to provision it.
