Doctrine throws an error for {function}

[nzakas]

Right now, Doctrine throws an error on this:

/**
 * @param {function} foo desc
 */

However, if you capitalize "function", then it's okay:

/**
 * @param {Function} foo desc
 */

This doesn't appear to be a problem with other types ("object" vs. "Object", "string" vs. "String").

Nice catch.
This is because function keyword is used for function syntax. We should take care about the above pattern.
