C-SPARQL query parsing error #15
Description
When registering C-SPARQL queries, the parser throws an error at the FROM STREAM keywords.
The grammar in https://github.com/streamreasoning/CSPARQL-engine/blob/master/csparql-core/Grammar/master.jj shows the following entry: <FROM: " from ">. Note the whitespace before "from": Adding this whitespace in the query works fine, i.e. FROM STREAM.
