Description

A scope is essentially a region in which certain functions and variables are active. You must have at least one scope for a calculator to function.

A scope inherits functions from its parent scope(s), and can use the variables from them, in priority of itself, then direct parent, etc.

For instance if we have the scope

   {{CalcScopeStart}}
     {{CalcFormula|abc|a + b}}
     {{CalcInput|a}}
     {{CalcScopeStart}}
       {{CalcInput|b}}
       {{CalcResult|abc}}
     {{CalcScopeEnd}}
     {{CalcScopeStart}}
       {{CalcInput|b}}
       {{CalcResult|abc}}
     {{CalcScopeEnd}}
   {{CalcScopeEnd}}

abc:a + b name=a;default=1

name=b;default=0 formula=abc;

name=b;default=0 formula=abc;

As you can see, there are two b variables, but the result only uses the b variable in its own scope. However, both use the a variable in its parent scope.
