        o  change source header 
		"The Spar Library - modular math parser"
	   to
	   	"The Spar Library - a maths applications C/C++ framework"
	   
	   with an AWK script??

	o  complete and extend the API programmer's manual

	o  variable arguments functions: use a simple linked list
           the output should be a series of values. For instance:

                24

           or 

                cos(1,2,3,4)
