* Resources are scalar values, scalar values are int, float or char
* Defined in include/mesos/mesos.proto
* How are resources/attributes defined in slaves/agents:
http://mesos.apache.org/documentation/latest/attributes-resources/

* Framework defined in include/mesos/mesos.prot LINE 208
* We are thinking of adding 'd_vector' in Framework Info

Types

The types of values that are supported by Attributes and Resources in Mesos are scalar, ranges, sets and text.

The following are the definitions of these types:

scalar : floatValue

floatValue : ( intValue ( "." intValue )? ) | ...

intValue : [0-9]+

range : "[" rangeValue ( "," rangeValue )* "]"

rangeValue : scalar "-" scalar

set : "{" text ( "," text )* "}"

text : [a-zA-Z0-9_/.-]

* Resources class is defined in resources.hpp in include/mesos
* Resources class LINE 312 'sum'
* // Get all the resources that are scalars.
  Resources scalars() const;

  // Get the types of resources associated with each resource name.
  // NOTE: Resources of the same name must have the same type, as
  // enforced by Resources::parse().
  std::map<std::string, Value_Type> types() const;

 // Helpers to get known resource types.
  // TODO(vinod): Fix this when we make these types as first class
  // protobufs.
  Option<double> cpus() const;
  Option<double> gpus() const;
  Option<Bytes> mem() const;
  Option<Bytes> disk() const;
CPUs, GPUs, Mem and Disk are SCALAR


Roadmap:
* Install Protobuff compiler .. Read the document!!
* How can 'd_vector' be defined: Resources d_vector;
  -> Modify the Protobuff, add some values in message frameworkInfo = CPUs, Mem, float values
    -> Modify Test Framework to add some lines to add the extra field in the Protobuff
  	-> Modify add() in sorter.hpp line 81
  	-> Modify function call in hierarchial.cpp line 259
* Modify sort algorithm in sort.cpp
