Introduce RecordOf to get record type from a table type

[adithyaselv]

Introduce RecordOf syntax to get record type from a table type.

eg:

Account := Type(RecordOf(Accounts));

Points := Type([{x : Number, y : Number}]); 
Point := Type(RecordOf(Points));
 distance(a: Point, b: Point): Number = Sqrt(Power(b.x-a.x, 2) + Power(b.y-a.y, 2));

RecordOf works only within a TypeLiteral . Lays foundations for future type helpers (eg: Union multiple record types ... ) that we may have.

• This ensures that we can avoid reserving RecordOf keyword in functions
• Avoids ambiguity when we move Named formula syntax to use := for example ,

  Account := RecordOf(Accounts);

  can mean type vs an UDF
