This work is based on the ol.expr package by @tschaub. It adds a few named expression functions to that package: * INTERSECTS, CONTAINS, DWITHIN, WITHIN (no client-side implementation as yet) * LIKE (like comparison with wildcard, singleChar and escapeChar) * IEQ (case-insensitive equality) * INEQ (case-insensitive non-equality) It also adds a few extra parameters to the existing EXTENT function to be able to deserialize and serialize all info (i.e. projection and property name). Some changes were needed for the GML parser as well: * createGeometry function needed to be public * when parsing Box (GML2) and Envelope (GML3) also parse the srsName * fix up writing for Box and Envelope now that bounds is an array Also added createDocumentFragment function to the XML parser. Implementation is similar to OpenLayers 2. Some addtional notes on the implementation: * PropertyIsBetween was implemented as an ol.expr.Logical with operator ol.expr.LogicalOp.AND and two ol.expr.Comparison instances with operator ol.expr.ComparisonOp.GTE and ol.expr.ComparisonOp.LTE * In OGC Filter And and Or can contain more than 2 sub filters, so this is translated into a hierarchy of ol.expr.Logical
