Also, fixed typo in configuration

- Added debug flag, when `true` returns in page SPARQL query as well as
results array

Right now, when http://example.org uses data with namespace
http://another.com
- Every time a SELECT is executed, it will change http://another.com to
http://example.org.
- This is not the case for DESCRIBE/CONSTRUCT
- N-Triples, Turtle and RDF/XML versions works fine so far

Problems:
- No description for new URI in http://example.org
- Not clear how to link URI in http://exampler.org to
http://another.com. Suggestion: `<http://example.org/abc> owl:sameAs
<http://another.com/abc>` . It is no clear __when__ to do it

instead of {{r[.INNERFILE].value.VARIABLE}}

now it will be {{r[.INNERFILE].VARIABLE.value}}

Conflicts:
	install.sh

Allow multiple/recursive queries
Allow use of multiple endpoints
Modified query tu support Haanga syntax
Fixed several bugs

just image for now

Model definition:

The new structure will be

models\
           |
           |
           \foaf:Person.model.html\
                                              |
                                              |
                                              \localQuery1
                                              \localQuery2
                                              \dbpedia\
                                                           |
                                                           |

\queryInDBpedia1

\queryInDBpedia1

Queries under the type subdir will be executed against the default
sparql endpoint
Quries under a subdir named an endpoint shortcut(*) will be ran against
that endpoint

(*) You need to define an endpoint in settings.inc.php

to query against your endpoint you need to define
$conf['endpoint']['mySparqlEndpoint'] = 'http://example.org/sparql';

Sparql endpoints are already defined for dbpedia and logd

Later you can create a subdirectory called 'mySparqlEndpoint' under a
model.

By aware that it is HIGHLY recommended to use only letters and numbers
(no periods, colons, etc.)

Also, fixing error in default template

Silly mistake: blank line at the end of file led to wrong RDF/XML (because document didn't stated w/ XML header

Adding templates dir
Removing owl:Class view and model to allow ln form rdfs:Class

Also, displaying results when there is only one class in special/index

Instead of iterate over a row like {0.000000or row in
r.filename}{{r.value.variable}}{4.659039e-321ndfor} when there is only
one row, it is possible to access the values from
{{r.filename.value.variable}}

Multiple queries

Instead of creating a file for the model, create a dir (e.g.,
foaf:Person.view.html). Inside add different files (the name doesn't
matter). In the view file, they will be accessed as r.filename and can
be operated as usual

Created symlinks to default.*.rdf so we have a unified query/view for
each format (although it still can be modified, but is a bad practice)

back to previous working commit

Test multiple queries

Instead of creating a new class, users only need to create a model and
view file called special.<COMMAND>.[view|model].extension  Thus, it is
possible to create new URL such as http://<HOMEURL>/special<COMMAND>

- Added "special" URIs where an API can be created -- Included an
abstract class from where these special URIs can be implemented --
Included a basic class that implements the abstract class -- So far,
only listing instances for a class is implemented - Root for website
redirection -- Now it goes to /special/index to list all classes - Moved
include of settings below in commons.inc.php so it can override values -
Created owl:Class and rdfs:Class' templates
