Problem:  typeinfo header file missing from ArrayData.I file

==========================================================
          <typeinfo> must be included before typeid is used
     if ( ( typeid(TYPE) == typeid(bool) ) |
            ^
          detected during instantiation of "bool  SAMRAI::pdat::ArrayData<DIM,
                    TYPE>::isStandardType() [with DIM=1, TYPE=double]"
==========================================================

Fix:   Include <typeinfo> in ArrayData.I.

Problem:  Declaration of lowers array in EmbeddedBoundaryGeometry.C 
          involves a non-const variable.

==========================================================
"/home/ktchu/software/samrai/SAMRAI-v2.1.0/include/EmbeddedBoundaryGeometry.C", line 2797: error:
expression must have a constant value
double lowers[(1 << area_ndim)][DIM];  // [ncorners][XYZ loc]
                                      ^          detected during
instantiation of "int
SAMRAI::appu::EmbeddedBoundaryGeometry<DIM>:: recursiveCalculateArea(const
double *, const double *, int, double &,  double &, int &) const [with DIM=1]"
==========================================================

Fix:  make area_ndim a const int.

-----------------------------------------------------------------------------

-----------------------------------------------------------------------------
Problem:  Declaration of inout array in EmbeddedBoundaryGeometry.C 
          involves a non-const variable.
==========================================================
"/home/ktchu/software/samrai/SAMRAI-v2.1.0/include/EmbeddedBoundaryGeometry.C", line 2918: error:
constant value is not known
        int inout[ncorners];
                        ^          detected during instantiation of  "int
SAMRAI::appu::EmbeddedBoundaryGeometry<DIM>::classifyCell(const  double *,
const double *) const [with DIM=1]"
==========================================================

Fix:  use bit shifting instead of computing ncorners at runtime:  

==========================================================
  int inout[1<<DIM];
==========================================================
