! Purpose: Allocates data structures for an individual interaction
!
! Description: none.
!
! Input: global    = global data
!        inrt      = interaction
!        nEdges    = number of Edges in interaction
!        nSwitches = number of integer parameters for interaction
!        nData     = number of real parameters for interaction
!
! Output: sets value of inrt%nEdges,
!         allocates and initializes inrt%edges, inrt%switches, and inrt%data
!
! Notes: none.
