PROBLEM STATEMENT
I want a list of BioServices that are associated with each KindOfInput (such
as "gene", "DNAFragment", "genome", etc.). What 
is available from my service provider is a list of strings, each
containing the name of a service followed by all the KindsOfInput it requires.

Given a vector <string> services, return a vector <string> in which each element contains a
KindOfInput followed by the names of all the services that use that kind of
input.  

Each KindOfInput should appear exactly once in the return. Within 
each element of the return, the service names should be in alphabetical order,
and should be separated by the 2 characters ", " (comma space). The KindOfInput should be
separated from the first service name by the 5 characters " ==> " (space eq eq gt space). The 
returned
list should be in alphabetical order.

Note that all names are case-sensitive, and that "alphabetical order" refers to
the ASCII ordering, where, for example, 'Z' precedes 'a'.




DEFINITION
Class:ServiceNames
Method:makeList
Parameters:vector <string>
Returns:vector <string>
Method signature:vector <string> makeList(vector <string> services)


CONSTRAINTS
-services will contain between 1 and 50 elements, inclusive.
-Each element of services will contain between 1 and 50 characters, inclusive.
-Each element of services will contain tokens separated by a single space (' ').
-Each token will consist of 1 or more letters ('A'-'Z' or 'a'-'z').
-The first tokens of the elements in services will be distinct.
-Within each element of services the KindsOfInput will be distinct.


EXAMPLES

0)
{"BLAST Genome Annotation Sensitivity","PING","X Annotation"}

Returns: {"Annotation ==> BLAST, X", "Genome ==> BLAST", "Sensitivity ==> BLAST" }




1)
{"PING"}

Returns: { }



   There are no KindsOfInput so the return has 0 elements.

2)
{"BLAST Genome annotation Sensitivity","PING","X Annotation","Apple X ample"}

Returns: {"Annotation ==> X", "Genome ==> BLAST", "Sensitivity ==> BLAST", "X ==> Apple", "ample 
==> Apple", "annotation ==> BLAST" }

annotation and Annotation are distinct kinds of input. annotation comes later alphabetically than 
any name that starts with an uppercase letter.
