Useful ancillary stuff

These include helper classes, typedefs, enums, and miscellaneous functions. More...

Classes
class	linalg_traits< T >
	Helper class defining relationships between numerical types; e.g. of what type is norm(T)? More...
struct	interval
	A class to define index-sets, specifically for subvectors and submatrices. More...
Typedefs
typedef std::complex< double >	complex
	A convenient synonym for std::complex<double>, complex is one of LinAlg's most important datatypes.
typedef unsigned int	itype
	The type of all index variables that run from 0 to N.
Enumerations
enum	MatrixStorageType {   Dense, UpperTri, LowerTri, Banded,   Sparse, PermScale, Other }
	An enumerated list of all the types of matrices we expect to support (someday), including "other".
Functions
void	ThrowError (char *errstring, bool fatal=false)
	A routine for easily printing an error string, and aborting if necessary.
void	Profile (char *methodname, int p1, int p2, double p3)
	Prints methodname, p1, p2, and p3 to "profile.log".
Variables
std::ofstream *	ProfileStream
	Output stream, used by Profile(), which opens it to "profile.log".
const complex	I
	Defined in linalg.cpp as std::complex<double>(0,1).
const double	Pi
	Defined in linalg.cpp as M_PI.
