Defines functions evalProposedPoints.OptState

# evals the points proposed by proposePoints
# (called by mboTemplate)
#
# @param opt.state
# @param prop: result of proposePoints
# @return [\code{numeric} | \code{matrix}] Numeric vector of y-vals or matrix
#   (for multi-objective problems).
#
# gets the getExtras, converts point data.frame to a list, repairs points out-of-bounds
# then call evalTargetFun
