Properties now uses PropertyFamily and contained classes.
Fetching,seting,clearing properties can be done with PropertyFamilyKey or PropertyTypeKey.
Hierarchy of newly added clases is:
Vertices -n-> PropertyFamily {name: String} <-1-n-> PropertyType {type: Property::Flags}
Edges -n-> PropertyFamily {name: String} <-1-n-> PropertyType {type: Property::Flags}
PropertyFamilyKey -> PropertyType
PropertyTypeKey -> PropertyType
PropertyType t0,t1;
let t0!=t1 be true
let t0.family==t1.family be true
then next is true
PropertyTypeKey{&t0}!=PropertyTypeKey{&t1}
PropertyFamilyKey{&t0}==PropertyFamilyKey{&t1}
PropertyFamilyKey{&t0}==PropertyTypeKey{&t1}
PropertyTypeKey{&t0}==PropertyFamilyKey{&t1}

Vertex::Accessor now updates Label index.

Applied changes for code review.
.FIX T67
.FIX T65
Modifed astar main for benchmark.
Experimented with map of best visited and confirmed:
-it is faster by 25%
-observed that it founds best resoult
-loses some non best resoults
Added convinent method at() to get property from RecordAccessor.
Method requires value_ref() method on property object.
DbAccessor:
-Guarantees that access to Vertex and Edge is possible only through
Vertex::Accessor and Edge::Accessor.
-Guarantees that changing Vertex and Edge is possible only using
Vertex::Accessor returned by vertex_insert() method and
Edge::Accessor returned by edge_insert() method.
-Offers CRUD for Vertex and Edge except iterating over all edges.
Squashed commit messages:
First step in database accessor refactoring done.
It's compiling.
All tests with exception of integration_querys pass
Tests now initialize logging facilities.
Refactored accessors.
RecordAccessor now has 3 states.
From,To,Out,In in there respecive Accessors return unfilled RecordAccessor.
Added iterator classes into utils/itearator/.
EdgeRecord now contains from,to fields as immutables.
Vertex in place of in vector of edges has in RbHashMultimap of edges.
Astar exepriment now uses real filters based on before mentioned map.
