Support Folding based on Regex

[dufferzafar]

I used these two rules in Sublime Text for folding code:

"fold_functions": {
    "find": "^function\\b(.*?(\\n))+.*?\\}",
    "greedy": false,
    "case": false
},

"markdown_links": {
    "scope": "markup.underline.link",
    "find": "([^\\n\\r]+)",
    "replace": "",
}

{
    "caption": "Reg Replace: Fold Markdown Links", "command": "reg_replace",
    "args": {"replacements": ["markdown_links"], "action": "fold"}
},

{
    "caption": "Reg Replace: Unfold Markdown Links", "command": "reg_replace",
    "args": {"replacements": ["markdown_links"], "action": "unfold"}
},

Is it possible to add support for code folding?
