Gtype() is extended version of the function getType. Gtype() can determine
some types which are not included in the function gettype(): integers, real
numbers, complex numbers, complex expressions and complex variables.

New additional types are:
	"CEXP"		complex expression
	"CNUM"		complex number
	"CVAR"		complex variable (only in Rectangular or Polar
					  Complex Format)
	"INT"		integer
	"REAL"		real number


The comparison of these functions is given in the next table:

expression			gettype(expression)	gtype(expression)
-------------------------------------------------------------------------
0,  -100,  3.			"NUM"			"INT"
2.57,  7/3			"NUM"			"REAL" 
pi,  2^(1/2)			"EXPR"			"REAL"
7-2i				"EXPR"			"CNUM"
x+5, sin(2k*pi)			"EXPR"			"EXPR"
x+5i, e^(x_)			"EXPR"			"CEXP"
x				"NONE" or "VAR"		"VAR"
x_				"NONE" or "VAR"		"CVAR" or "VAR"

Other types are identical for both functions.
