 5.b Design of Term
 A term in JavaCalculus follows the below grammar:
-  M*x^Exp*IndConstant*Parenthesis
+  M*x^Exp * IndConstant * Parenthesis
 Where M: is a numerical String ( A constant integer or float)
       X: is the prmary variable (used only by differentiator & Integrator- variable “DiffWithRespTo” in the code- can be alphanumeric as in x123, y256 etc (i.e of any length).)
 IndConstant: is any other variable(other than the primary variable (x) ). These are treated as constant string during Integration & Differentiation i.e Algebraic Coefficients.
