Handle multiple subfolder

[ColColty]

In the json file we can add diferent subfolders to use all of that

For example if we have a varaible for each subfolder of:

src/components
src/utils
src/helpers

And in the make file we have a varaible for each one:

COMPONENTS_SRC = 
UTILS_SRC = 
HELPERS_SRC =

In the json we would be able to add:

{
    "src": {
        "components": {
             "folder": "components",
             "variable": "COMPONENTS_SRC\t=",
             "path": "\t$(SRC_DIR)/components/"
        },
        "utils": {
             "folder": "utils",
             "variable": "UTILS_SRC\t=",
             "path": "\t$(SRC_DIR)/utils/"
        },
        "helpers": {
             "folder": "helpers",
             "variable": "HELPERS_SRC\t=",
             "path": "\t$(SRC_DIR)/helpers/"
        },
        "lib": "...",
        "tests": "...",
}
