// Module:  stdlib/nn/gru_cell.tern
// Purpose: Ternary Gated Recurrent Unit (GRU) Cell
// Author:  RFI-IRFOS
// Ref:     https://ternlang.com

// Simpler than LSTM. Gates output ternary states.
// 'tend' provides a natural leak/drift mechanic without floating point math.

    // tend = partially ignore

    // Balance between old and new state
