// This definition describes the default TNT data type used for
// indexing into TNT matrices and vectors.  The data type should
// be wide enough to index into large arrays.  It defaults to an
// "int", but can be overriden at compile time redefining TNT_SUBSCRIPT_TYPE,
// e.g.
// 
//      g++ -DTNT_SUBSCRIPT_TYPE='unsigned int'  ...

// () indexing in TNT means 1-offset, i.e. x(1) and A(1,1) are the
// first elements.  This offset is left as a macro for future
// purposes, but should not be changed in the current release.
