alasql.parse() instead alasql()

[agershun]

We can use AlaSQL parser() function instead execution function alasql() to test SQL syntax. The syntax is:

    var ast = alasql.parse('SELECT * FROM one');

Good idea.

I will change that.

I am running a test on all test files with alasql.parse() to see what work we have with the parser
