description: BackendDAEUtil comprised functions for BackendDAE data types.
RCS: $Id$
This module is a lowered form of a DAE including equations
and simple equations in
two separate lists. The variables are split into known variables
parameters and constants, and unknown variables,
states and algebraic variables.
The module includes the BLT sorting algorithm which sorts the
equations into blocks, and the index reduction algorithm using
dummy derivatives for solving higher index problems.
It also includes the tarjan algorithm to detect strong components
in the BLT sorting."
