Description: Implements a four-stage pipeline for probabilistic seismic
  performance analysis of slopes and embankments. The package takes a
  uniform-hazard spectrum at multiple return periods as input (any
  source) and produces: (1) synthetic soil profile generation and
  fundamental period estimation from USCS classification via Ishihara's
  small-strain shear-modulus model and the inhomogeneous truncated
  shear-beam theory of Gazetas and Dakoulas; (2) nonlinear site
  amplification using the Seyhan & Stewart (2014) model
  <doi:10.1193/063013EQS181M>, with inter-period correlation via
  Baker & Jayaram (2008) <doi:10.1193/1.2857544>; (3) Monte Carlo
  ensemble of six empirical Newmark sliding-block displacement models

   and the Bray and Macedo shallow-crustal update) with coherent
  correlated draws; (4) log-log inversion to the performance-based
  seismic coefficient kmax at user-specified displacement targets. All
  outputs are 'data.table' objects.
