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.
1.
Applied changes for code review.
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/.
