  Text, notes, and mana are obvious. The rest:

  * {target}: one of [task, self, party, user]. This is very important, because if the cast() function is expecting one
    thing and receives another, it will cause errors. `self` is used for self buffs, multi-task debuffs, AOEs (eg, meteor-shower),
    etc. Basically, use self for anything that's not [task, party, user] and is an instant-cast

  * {cast}: the function that's run to perform the ability's action. This is pretty slick - because this is exported to the
    web, this function can be performed on the client and on the server. `user` param is self (needed for determining your
    own stats for effectiveness of cast), and `target` param is one of [task, party, user]. In the case of `self` spells,
    you act on `user` instead of `target`. You can trust these are the correct objects, as long as the `target` attr of the
    spell is correct. Take a look at habitrpg/src/models/user.js and habitrpg/src/models/task.js for what attributes are
    available on each model. Note `task.value` is its "redness". If party is passed in, it's an array of users,
    so you'll want to iterate over them like: `_.each(target,function(member){...})`

  Note, user.stats.mp is docked after automatically (it's appended to functions automatically down below in an _.each)

User (prototype wrapper to give it ops, helper funcs, and virtuals
------------------------------------------------------
 */


/*
User is now wrapped (both on client and server), adding a few new properties:
  * getters (_statsComputed, tasks, etc)
  * user.fns, which is a bunch of helper functions
    These were originally up above, but they make more sense belonging to the user object so we don't have to pass
    the user object all over the place. In fact, we should pull in more functions such as cron(), updateStats(), etc.
  * user.ops, which is super important:

If a function is inside user.ops, it has magical properties. If you call it on the client it updates the user object in
the browser and when it's done it automatically POSTs to the server, calling src/controllers/user.js#OP_NAME (the exact same name
of the op function). The first argument req is {query, body, params}, it's what the express controller function
expects. This means we call our functions as if we were calling an Express route. Eg, instead of score(task, direction),
we call score({params:{id:task.id,direction:direction}}). This also forces us to think about our routes (whether to use
params, query, or body for variables). see http://stackoverflow.com/questions/4024271/rest-api-best-practices-where-to-put-parameters

If `src/controllers/user.js#OP_NAME` doesn't exist on the server, it's automatically added. It runs the code in user.ops.OP_NAME
to update the user model server-side, then performs `user.save()`. You can see this in action for `user.ops.buy`. That
function doesn't exist on the server - so the client calls it, it updates user in the browser, auto-POSTs to server, server
handles it by calling `user.ops.buy` again (to update user on the server), and then saves. We can do this for
everything that doesn't need any code difference from what's in user.ops.OP_NAME for special-handling server-side. If we
*do* need special handling, just add `src/controllers/user.js#OP_NAME` to override the user.ops.OP_NAME, and be
sure to call user.ops.OP_NAME at some point within the overridden function.

TODO
  * Is this the best way to wrap the user object? I thought of using user.prototype, but user is an object not a Function.
    user on the server is a Mongoose model, so we can use prototype - but to do it on the client, we'd probably have to
    move to $resource for user
  * Move to $resource!

    /**
     * Creates a `lodash` object which wraps the given value to enable intuitive
     * method chaining.
     *
     * In addition to Lo-Dash methods, wrappers also have the following `Array` methods:
     * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`, `splice`,
     * and `unshift`
     *
     * Chaining is supported in custom builds as long as the `value` method is
     * implicitly or explicitly included in the build.
     *
     * The chainable wrapper functions are:
     * `after`, `assign`, `bind`, `bindAll`, `bindKey`, `chain`, `compact`,
     * `compose`, `concat`, `countBy`, `create`, `createCallback`, `curry`,
     * `debounce`, `defaults`, `defer`, `delay`, `difference`, `filter`, `flatten`,
     * `forEach`, `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`,
     * `functions`, `groupBy`, `indexBy`, `initial`, `intersection`, `invert`,
     * `invoke`, `keys`, `map`, `max`, `memoize`, `merge`, `min`, `object`, `omit`,
     * `once`, `pairs`, `partial`, `partialRight`, `pick`, `pluck`, `pull`, `push`,
     * `range`, `reject`, `remove`, `rest`, `reverse`, `shuffle`, `slice`, `sort`,
     * `sortBy`, `splice`, `tap`, `throttle`, `times`, `toArray`, `transform`,
     * `union`, `uniq`, `unshift`, `unzip`, `values`, `where`, `without`, `wrap`,
     * and `zip`
     *
     * The non-chainable wrapper functions are:
     * `clone`, `cloneDeep`, `contains`, `escape`, `every`, `find`, `findIndex`,
     * `findKey`, `findLast`, `findLastIndex`, `findLastKey`, `has`, `identity`,
     * `indexOf`, `isArguments`, `isArray`, `isBoolean`, `isDate`, `isElement`,
     * `isEmpty`, `isEqual`, `isFinite`, `isFunction`, `isNaN`, `isNull`, `isNumber`,
     * `isObject`, `isPlainObject`, `isRegExp`, `isString`, `isUndefined`, `join`,
     * `lastIndexOf`, `mixin`, `noConflict`, `parseInt`, `pop`, `random`, `reduce`,
     * `reduceRight`, `result`, `shift`, `size`, `some`, `sortedIndex`, `runInContext`,
     * `template`, `unescape`, `uniqueId`, and `value`
     *
     * The wrapper functions `first` and `last` return wrapped values when `n` is
     * provided, otherwise they return unwrapped values.
     *
     * Explicit chaining can be enabled by using the `_.chain` method.
