Generate DLaB's type of QueryExpressionFactory

[rappen]

An idea by @daryllabar.

What would it take for me to be able to add my own custom QueryExpression Helpers as an option?

Would YOU use it? Thumbs up if so!

He sent me an example:

var qe = QueryExpressionFactory.Create<Account>(a => new {
        a.Name,
        a.Address1_City,
        a.PrimaryContactId,
        a.Telephone1,
        a.AccountId
    },
    Account.Fields.StateCode, query_statecode,
    new ConditionExpression(Account.Fields.Address1_Line1, ConditionOperator.Null));

var par = qe.AddLink<Contact>(c => new {
        c.EmailAddress1,
        c.FirstName,
        c.LastName
    },
    Account.Fields.PrimaryContactId, Contact.Fields.Id);
par.AddColumns<Contact>();
par.WhereEqual(
    new ConditionExpression(Contact.Fields.FullName, ConditionOperator.NotEqual, query_0_par_fullname)
    new ConditionExpression(Contact.Fields.Address1_Country, ConditionOperator.Like, par_address1_country));

var R = par.AddLink<rapp_Rocket>(c => new {
        c.rapp_Number
    },Contact.Fields.ContactId, rapp_Rocket.Fields.rapp_ContactId);
R.WhereEqual(new ConditionExpression(rapp_Rocket.Fields.rapp_Nane, ConditionOperator.NotNull)

qe.AddOrder(Account.Fields.Name, OrderType.Ascending);
