CQL: Parser falsely interpretes "from" in entity name

Summary

Consider a property with a name with the string "from" in it, e.g., HeightFromBottom. Using this property in a SELECT query like SELECT HeightFromBottom FROM RECORD results in a parser error

mismatched input 'from' expecting {<EOF>, WITH_A, WHERE, WHICH, HAS_A, '.'}

since the parser misinterpretes the "from" in the selector.

Expected Behavior

Only the FROM surrounded by whitespaces should be recognized.

Actual Behavior

The first occurrence of the string "from" is connected to the SELECT.

Steps to Reproduce the Problem

Simply type the above query and execute. E.g., https://demo.indiscale.com/Entity/?query=SELECT%20HeightFromBottom%20FROM%20RECORD.

Specifications

• Version: LinkAhead 0.13
• Platform: any

Possible fixes

Parse for whitespaces around FROM.

Workaround

For the time being, selectors containing "from" need to be quoted. I.e., SELECT "HeightFromBottom" FROM RECORD works without problems.
