/*
Given a node in the AST, it replaces all function calls with the corresponding expression from the fct2Var mapping.
Since we traverse in order of function evaluation, all nodes that are lower in the subtree are supposed to
have been mapped, since they have already appeared in the list. Also, we only replace the shallowest level of
function calls in the surrent subtree, since we assume that replaceFunctionCallsInExpression  has already been called
for each of the subtrees rooted at the shallowest function calls lower than the current node:

E.g.: f(g(h(i))) + 5
has the AST:
     +
    / \
  fc1  5
  / \
 f  fc2
    / \
   g  fc3 
      / \
     h   i
where fc? represents an SgFunctionCallExpression. Order of function evaluation is h(i), g(_), f(_).

Calling 'replaceFunctionCallsInExpression' on '+' will generate
                     temp_var + 5
but calling the same function on 'fc2' will generate
                     f(temp_var) + 5
