websql-sugar

Use this to build data access layers on top of websql, e.g:

``javascript
var db = require('websql-sugar')({ name: 'mydb', version: '1.1' })

module.exports = {
listScans: function (cb) {
// readonly api
// select queries can be issued from newTx() too
// the singleSelectCallback will require the user of the result to write less boilerplate code
// and just handle the actual data
db.newRtx().query('SELECT * FROM scan').execute(db.singleSelectCallback(cb))
},

insertFoo: function (x, y, cb) {
db.newTx()
.query('INSERT INTO foo (x, y) VALUES (?, ?)',[x, y])
.execute(db.singleInsertCallback(cb))
},

updateScan: function (endTime, infected, id, cb) {
db.newTx()
// can just pass the arguments if they appear in the same order of the query parameters
.query('UPDATE scan SET end=?, infected=? WHERE id=?', arguments)
.execute(db.singleSelectCallback(cb))
}
}
``

1. who designs properties that throws exceptions? printing objects is like walking in a mine field and that is exactly what happens in a websql query result!

2. the callbacks are not in node.js convention :(
