Category calculations

The fifth and final section contains functions to calculate totals by category, which we'll utilize in the pie charts, as follows:

void upsertCategoryNode(int categoryId, float transactionRaw,                        float transactionCooked) {    struct Node *foundNode = findNodeById(categoryId, categoriesHead);    if (foundNode != NULL) {        foundNode->rawAmount += transactionRaw;        foundNode->cookedAmount += transactionCooked;    } else {        appendNode(&categoriesHead, categoryId, categoryId, transactionRaw,                   transactionCooked);    }}void buildValuesByCategoryList() {    struct Node *node = transactionsHead;    while (node != NULL) {        upsertCategoryNode(node->categoryId, node->rawAmount,                           node->cookedAmount);        node = node->next;    }}void recalculateForCategories() { categoriesHead ...
