Deprecate alternatives syntax for the comparison predicate
----------------------------------------------------------

                 Key: GEOT-3501
                 URL: http://jira.codehaus.org/browse/GEOT-3501
             Project: GeoTools
          Issue Type: Improvement
          Components: core cql
    Affects Versions: 2.7.0
            Reporter: Mauricio Pazos
            Assignee: Mauricio Pazos
            Priority: Minor


The OGC CQL Syntax defines the followings rules for comparison predicate:
   < NOT: "not"|
   < EQ: "="> |
   < NEQ:"<>" > |
   < GT: ">" > |
   < LT: "<" > |
   < GTE: ">="> |
   < LTE: "<="> 

Nowadays, the CQL syntax supports the following alternatives:

   < NOT: "not" | "!"> |
   < EQ: "eq" | "==" | "="> |
   < NEQ: "neq" | "<>" > |
   < GT: "gt" | ">" > |
   < LT: "lt" | "<" > |
   < GTE: "gte" | ">="> |
   < LTE: "lte" | "<="> |
ECQL does not support these alternatives.

These alternatives are not published neither in the geotools docs nor in the 
OGC specifications. In order to avoid confusion I will deprecate these 
alternative.
