type of TS problem that is solved

### Synopsis

    typedef enum {
      TS_EQ_UNSPECIFIED               = -1,
      TS_EQ_EXPLICIT                  = 0,
      TS_EQ_ODE_EXPLICIT              = 1,
      TS_EQ_DAE_SEMI_EXPLICIT_INDEX1  = 100,
      TS_EQ_DAE_SEMI_EXPLICIT_INDEX2  = 200,
      TS_EQ_DAE_SEMI_EXPLICIT_INDEX3  = 300,
      TS_EQ_DAE_SEMI_EXPLICIT_INDEXHI = 500,
      TS_EQ_IMPLICIT                  = 1000,
      TS_EQ_ODE_IMPLICIT              = 1001,
      TS_EQ_DAE_IMPLICIT_INDEX1       = 1100,
      TS_EQ_DAE_IMPLICIT_INDEX2       = 1200,
      TS_EQ_DAE_IMPLICIT_INDEX3       = 1300,
      TS_EQ_DAE_IMPLICIT_INDEXHI      = 1500
    } TSEquationType;

### Developer Notes

this must match petsc/finclude/petscts.h

### Supported types are

TS_EQ_UNSPECIFIED (default) TS_EQ_EXPLICIT {ODE and DAE index 1, 2, 3, HI}: F(t,U,U_t) := M(t) U_t - G(U,t) = 0 TS_EQ_IMPLICIT {ODE and DAE index 1, 2, 3, HI}: F(t,U,U_t) = 0
